I have a 1965 Mustang Convertible with a 289ci/c4 auto trans. Before I bought it, someone had switched it to a 2bbl setup. I am in the middle of converting it back to a stock 4bbl intake/carb.

However, I am missing some pieces.

I have the carb and the intake. I am told I am missing the rod that goes from the carb to the driver's side of the transmission (kick down rod) and the ball "knob" that's needed to make my FoMoCo carb work with my automatic trans. My car does not have the cable setup - it's a solid rod (66 went to the cable). Basically, I am missing the whole kick down system. I am also not sure if I need to switch out the throttle linkage from my 2bbl to a 4bbl or if they are the same.
I have been told by my mechanic and by the guy who sold me my new FoMoCo 4100 carb that I am needing the entire Kick-down system
form the trans to the Carb. Consists of tranny kick-down lever on tranny,
to linkage arm(long one), to pivot w/bracket, to linkage arm (short-several
different lengths to choose from and Ends) to Carburetor "Ball" on throttle
arm.

Does anyone have a diagram or photos that would show me what I am looking for? Since I have never seen a CORRECT setup, I am not honestly sure what I'm asking for.

I need to procure these parts ASAP, but no one seems to have them in the repro market, so I'm down to searching used. Any ideas? No junk yards near me...

Thank you for your time.

Please respond ASAP. This car is committed to being in a wedding July 2 and I need to get it put back together ASAP.

Thanks,
Sheila

Well, I can't help you find the parts, and I don't have any pictures or diagrams for you, but I will contribute this. The throttle linkage and kickdown linkage are the same for 2V and 4V. The only difference I can think of is the spring bracket that attaches to the carb mounting stud. The bracket is available in repro, but a simple bracket can easily be made. Hope that helps.

I don't believe that there is a 1.08 Mustang 4100 with a kickdown linkage on it for the transmission. To my knowledge, all 65-66 Mustangs use the kickdown on the throttle linkage rather than on the carb like big cars and trucks. NPD part number is 9725-2 on the proper linkage. Here's a link, but it probably won't work.http://npd.dirxion.com/WebProject.asp?BookCode=mtg09flx#
Page 122 of their latest and greatest catalog.
it is easy to find a 2bbl carb with the kickdown on the carb, but a 1.08 4bbl is scarce or non-existent. There is just a small adjustable cable that runs from the accelerator pedal mechanism to the transmission. Very easy to do with the right stuff. Don't mess with the carb at all!
There's a good diagram on page 122 of the whole assembly you need.

 

[eeyore2123]

Thanks for the link and the info.

However, that diagram pictures the setup used in LATE 65 and 66. My car is an early 65, which used the hollow rod from the carb to the driver's side of the trans.

Apparently this part is non-existant.

I am told that this part connects to the carb via a ball "knob" on the throttle or something.

I have yet to find a good diagram of this style.

Any ideas?

 

[eeyore2123]

I have seen the term "bell crank assembly" and have been told that's what I am looking for. Probably still non-existant for the early 65 automatic cars, right?

What is so difficult about this part? It's a hollow tube...that looks fairly easy to machine. That's why I can't figure out why it's not in reproduction. I'm not a machinest, or I would already have made one!

 

[eeyore2123]

I found the following information at another site I've been watching...which directly describes what I am looking for:

"Concerning the kickdown linkage, it's a vertical rod linked on a small arm on the gearbox side and to an articulated V fixed with two bolts on the top of the engine, parallel to the linkage of the accelerator. The V part just get a small hole on the carburettor side ! Either it should be linked to the carburettor or to the accelerator rod !!! Adjustment seems to be done by the thread on the vertical rod onto the V part.
I've been told it can be the same than on the Galaxie 1964 but I'm unable to find a sketch of it !!!

This is a 64 1/2 and 65 Mustang only linkage. From looking at the small exploded view that I found, the vertical rod connects to the articulated "V", which is mounted to the top of the intake manifold. From what I can tell the small hole in the "V" that is on the carb side is for a return spring that mounts from the "V" forward to a small bracket that mounts to, I think, the top valve cover bolt that is directly across from the carb. This keeps the "V" pulled forward.

The kickdown is actuated by the forward portion of the "V" resting against and between the two right angle bends in the middle of the throttle linkage. This is the linkage that is connected to the carb. and goes rearward to the gas pedal linkage. It just rests against that horizontal throttle linkage with the return spring keeping it positioned against the linkage itself. There is no fastener holding the "V" to the linkage, it just rests against it.

There is another separate, but similar, return spring for the throttle linkage that is hooked to another small bracket that is mounted onto the rear carb stud and from there goes rearward and hooks to the horizontal throttle linkage between the two right angle bends where the "V" rests.

When you press on the gas pedal the carb (Horizontal) linkage moves to the rear and pushes against the "V" which pushes down on the vertical rod. The rod in turn pulls the transmissions kickdown lever forward."

It's a bad picture but I think this is what you are looking for:

 

[68RCodeConv]

If all you want is functionality Lokar makes a great kickdown cable kit. Those kickdown rods are a pain.

 

[EastCoastClassic]

66candies photo is what you need.On the early cars they called it a bellcrank assembly. The hollow tube connected to the actual carb is a very common misconception,The hollow tube setup was used on Full size and possibly other Fords? The hollow tube was never used on 64-66 Mustangs although "Experts" will tell you other wise.

That said I have a complete working setup on my wifes car if you need any reference.I also happen to have a complete setup that I would sell or trade,I know this is the wrong section,(sorry)for transactions.

Here is a picture of the bellcrank that attaches to the intake manifold (2V or 4V)
http://pic80.picturetrail.com/VOL847/1785303/3437215/166250058.jpg
The bellcrank is moved via the throttle rod, not any attachment to the carb. The whole ball stud attachment is incorrect.

Here is a picture of the rod and how it goes from the bellcrank to the arm on the shifter input on the transmission.
http://pic80.picturetrail.com/VOL847/1785303/3437215/166038148.jpg

The kickdown linkage is made up of the following parts:
-Bellcrank
-Bellcrank return spring & bracket(attaches to the middle top valve cover bolt)
-Kickdown rod
-Attaching arm that attaches to the transmission shifter input shaft

Hopefully this will help. If you need any pictures in a larger format, let me know. These assemblies turn up from time to time on eBay or here. If thekid has a set-up for sale, get it.

I am just curious....is this setup why the throttle linkage has the step sideways in it?

 

[C7ZZ-F]

yes on the step. ivygreen's photos are exactly what you need.

 

[eeyore2123]

Ivygreen -
Thank you so much for taking time to send me the photos. I think this is exactly what I'm looking for. The guy who sold me the 4100 carb was the one who said I needed the ball "knob" thing. I don't know.

My mechanic told me that the 4100 I got was set up for a standard shift car -- that I needed something like an adapter kit (available for Holley/Edelbrock) to make it work for my automatic.

See where the confusion sets in? I'm caught in the middle trying to chase down parts I'm not really sure about.

If possible, could you please take photos of your setup without the air breather on the carb? I would like to see the linkage side of the carb to see if I have everything I need.

Right now all I have is a bare 4100 carb and a correct intake that is also bare.

Thank you again so much.

I have added a photo of my carb so you can get an idea. http://www.creativeflairdesign.com/65mustang/images/carb.jpg

 

[eeyore2123]

thekid,
You state that you have a complete setup for sale/trade.

Can you provide photos of it?

Price? Shipping to Kansas?

Please reply or email me.

Thanks.

Hi,
I will try to dig it out this weekend. I have never been able to post photos on this site? That said if you would like you can email me direct at poni1966@juno.com.

For clarification reasons in my first response I wrote How I was told by the "Experts" (Mechanics,restorers, even Holley corp.) That early Mustangs (64-67) Need a special linkage on the actual carb for autos.This is true on other Fords of the era(Galaxies,etc.) But not on Mustangs. A carb for manual trans Mustang swaps with one for an auto no questions asked(The differences are internal,Booster venturi's,jets,etc.).The question lies in the kickdown linkage which in both cases is handled via the actual throttle/pedal linkage depending on which setup you have and not the carb? Early :Using the bellcrank(like yours) or later which uses a cable that attaches to the bottom of the pedal linkage. Holley has been shooting themselves in the foot for years by misinforming early Auto equipped Mustang owners.

 

[EastCoastClassic]

Most importantly. This site is loaded with Hardcore Mustang geeks. I'm not doubting your mechanics mechanical abilities,as a mechanic he works on /look at tons of different cars.Most of us on here have been messing with these specific cars for years and we know all of the hardware,linkage,L Changes(assembly line changes),etc.that affected these cars. So when in doubt trust the general consensus on this site.

sorry to hijack a thread but
is the cable setup generally better than the rod setup? I have a 64 1/2 with c4 and edelbrock carb, I had to come up with some rigging to make mine work, ive seen some hotrods with the lokar setup and they look pretty cool.

 

[AzPete]

The Lokar setup works good and is a dream to adjust. I think they are pricey and as the only "modern" item under the hood, they look out of place. A friend has one on his 64.5 Vert that I have been working on. Even with the chrome air cleaner and valve covers, it looks out of place.

 

[jamison42166]

heck to most purists my whole engine compartment looks out of place to them.

I was really getting nervous reading this thread... I just went from a 2 to a 4 and the only thing connecting my carb to my kickdown are the two springs below, no ball-joint or whatever...
