One strange thing. Supposedly no 6 cyl '66's came with disk brakes but the pedal in this car says "Disk"?

They did not. Pedal pads can easily be changed. After I finich putting the disks on our car, its getting a disk brake pedal pad..

 

OK. If they actually converted it, I'll never know.

 

If you just want to go back to stock, there are lots of Mustang Six front end parts out there. With all the V8 conversions being done, there are whole six cylinder car front ends, some with with brakes and everything, literally left to rot or being given away for free. Some people try to sell them, but there are few takers. Watch your local Craigslist and stuff.

 

Thanks. Got to believe there is although I haven't found one yet. Maybe have to call around as no one seems to advertise one right now.

 

Just something to keep in mind - the sixes came with 4 lug wheels and the V8s with 5. So if it still has the original rear axle it's going to be 4 lug.

When you're looking at new parts if they're 5 lug you might want to replace the rear end too so that all four rims match. If you go back with original six cylinder parts it won't matter but if you start mixing and matching things can get mismatched on you.

Now if a previous owner did a V8 conversion and swapped out the rear then you'd be fine with new 5 lug parts in the front, but you'd be mismatched if you went back with original six cylinder parts.

Just know that there were differences and get the new parts that make your life easier based on whatever's currently on the car.

 

Thanks. Has 4 lug rear. That was another issue I was aware of. Not sure which way I'll go yet.

 

Appears to be a disc/drum master cylinder by the two different size reservoirs, rear portion would go to the front discs. Front small section to the rear drums.

 

That looks like there might be an adjustable proportioning valve just to the right of the master cylinder. If that's what it is someone's definitely already upgraded the brakes because that's not a stock Ford part.

 

Thanks all.

 

Putting in new parts for front end. 66 Mustang came without a front end so don't have that experience taking it apart and remembering how things went together. Have manuals but pictures aren't always clear enough. Right now I have a question on the upper spring saddles. Symmetric except they have a one tab which I assume is a guide for the brake cables? The orientation of the tab is not obvious and no pictures show it installed. Anyone no the proper orientation: for/aft and in/out?

Also, anyone know if there is a standard hardware list (nuts and bolts)?

Thanks

 

OK. Figured out the saddle question. It was actually a dumb question.

But now a new problem and searching the forum and vendors, just getting more confused. Got a tie rod rebuild kit but inner tied rod are different than ones came with the car (again, most front end missing so don't know what's right) Somewhere I saw that all 66 mustang tie rod threads are 11/16 which the old parts were. My kit came with all 1/2 inch threads except for the adjusting sleeves which are 11/16. Vendor claims right part and searching the web, a lot of them say 1/2 threads. Can anyone de-confuse me? What's right?

 

More strange PO stuff: Casting number indicates a 66 (or 8, hard to read) block from a Falcon but the head cast (integral with intake manifold) indiocates a 73 Falcon head. This makes sense? Think I have a head gasket leak but can't find that that engine or manifold was use on a 73 Falcon.

 

73 Falcons used a different engine for sure.

 

I haven't been following this thread. I assume you learned that the 65/66 6 cylinder tie rod threads are 1/2 inch and 8 cylinder threads are 11/16 inch.

You don't understand Ford's identification system. C8 indicates the part was first designed for the 1968 model year and that part may still have been in use 20 years later still wearing the C8 code. C8D means that the Falcon division was responsible for the design of the part but that part was used on every 6 cylinder engine regardless of which car the engine was installed in- Falcon, Mustang, Maverick, Fairlane, etc.
You have to read the date code that is cast or stamped into each part to determine when it was actually made. Your C8 block probably has a 1973 or later casting date code.
As far as parts for it are concerned just look for parts for any Ford car that used that engine. Like a 1973 Maverick.

 

I'm pretty sure the head gasket is the same for all of the 144/170/200/250 heads from 1960-1983. At least that's what Fel-Pro wrote on the label on the one sitting in my garage.

 

Thanks
Glad somebody understands it.

Thanks. That was my concern.

 

"75-82 Granola"? Man, I have HUNTING for one those everywhere!

 

Have a 66 convertible with no front end. Previous owner sold it along with the original 6 cyl engine. I just got a 67 200 cid engine and have a 5 speed - so getting there with that.

Thought I had a plan to get an IFS kit with disk brakes, rack and pinion, etc.: basically the whole front end suspension, steering and brakes. Just learned, however, that none of these kits work with the 6 cylinder and the standard (Mustang II) spindles they most seem to use still end up with a 2 inch drop. This is just a cool driver for my wife, not a hot rod. Just looking for safety and street handling and don't want the drop. Any suggestions? The more I research the more confused I get. Great if someone sold a complete affordable kit or, at least, a parts list I would need. Also CJpony sells the disc brake kit and OEM front suspension kit for 6 cylinder.

One strange thing. Supposedly no 6 cyl '66's came with disk brakes but the pedal in this car says "Disk"?

Nice idea. I’ve built a 200 6 cylinder, adding a T5 from an 87 Mustang GT. I have built the rear differential with a 3.55 gear. I will use a 2 barrel carb and split header from Clifford 6=8. And a Duraspark II ignition system. You will need a 9” bell housing to accommodate that 5 speed. I’m using Morden Drive Lines kit with adapter plate for the T5

 

Bell housing I got with the 6 worked. Forget why I didn't use the one that came with the T5. Got adapter kit, etc. Car is drivable now. just need a few details and bugs to work out.

 

Ok I had to buy a used 200 6 cylinder and build it. I bought a Dagenham 9” bell housing. Did you use MDL adapter kit? I’m still working sheet metal and front suspension, brakes and steering.

 

I just had to buy a spacer between the transmission and bell housing. Think from California Pony. Few years ago so not sure. Bought a disk conversion for the front. Used mechanical clutch for now. Power master won't fit with mechanical linkage. Dual cylinder though. Clutch is stiff for my wife (car is for her). Would like hydraulic but don't like slave inside bell. Found one outside but issues with backward clutch throughout. Also, don't want to spend thousands.

 

I get it! This 66 I’m building is for my wife too. She is also a 66 model 😂. I like the fact that we are building two cars that are very similar. I’m about to order my new front suspension.
