I have discovered some oddities on my new 65 coupe. It seems my car was built right at the crossover between 64.5 and 65,

The repop door tag has a build date of 15H - 15 Aug 64. My unit number is 262032.

I have beveled headlamp buckets, I do not have the original hood.

The horns are in front of the core support.

The core support has battery cooling vents.

I have a A on my vent knob.

The spare tire hold down is slotted, not a j-hook.

I have an alt.

My original color is O-Tropical Turquoise, I doubt that the PO knew how rare that color was when he painted the car Mercedes Red. I found the TT in the trunk under the package tray, maybe it will find its way back on one day.

Is there anything else that is 64.5 that may have found its way onto my 65?

Build date

Missed it by 1 day! Aug 14th was the last "noted" day of 64 and Aug 15th was the 1st of 65's. There are a lot of 64 parts on these cars, as they were using whatever they had and, at that time, there was no 64/65 delineation. Mine is Aug 13th, C code with alternator but like yours, a batch of 64 parts were still used. Dearborn was the only plant using the 64 hood with the turned down lip. All other plants used 65 style, but you can see major differences- smaller indents under the hood, no holes for hood lip molding and look for the date code at the back on the driver's side. Having the battery cooling vents is a rarity. Alternators were added about 2 weeks before this date.

I have a fiberglass hood, and a upgraded brake system, so many of the original parts are missing.

Hmm, I have an early 65, April 12 64 build date to be specific and I'm trying to think of differences...

I have the stationary passenger seat which I think was a pretty early change, like May or June of 64, the carpet is a little different; I have vinyl between the sill plates and the floor and I believe later ones were "wall to wall" carpeting. I seem to remember a difference in the blower motor as well but I can't remember exactly what. I want to say the windshield wipers were slightly different as well, not how they work but how the blades attach to the arms.

I'm sure there's more but that's all I can think of for now.

Most of these are not 64 1/2 parts. They were used a long time into production.

My October 64 fastback has all of them except the beveled headlamp buckets.

It was not uncommon at all to find '64 1/2 Parts on an Early '65 Production Car.. In fact, It's quite common. Old '64 1/2 parts that were usable got used up...It's as simple as that.. At the time of the '64 1/2 to '65 Changeover, Demand far outweighed actual production. They literally could not build the cars fast enough.

"Dearborn was the only plant using the 64 hood with the turned down lip. All other plants used 65 style,"


This is new to me. I have a September '64 built San Jose car complete with beveled headlight doors and turn down hood.

If I understand it correctly the only reason for the beveled headlight doors was because of the turn down on the hood. So why would the San Jose plant have beveled headlight doors if none of their hoods would require them?

Yeah, I don't think that's correct either... San Jose also used '64 1/2 Hoods as well and '64 1/2 Headlight Buckets.. albeit only for a few weeks of production which was only a couple of hundred cars..

Metuchen was the last Plant to come online and did not produce any '64 1/2 Mustangs.

See the chart below from the MPG (Mustang Production Guide):

I thought Mustangs and Falcons were built on the same line. Were Fairlanes also on the line?

What is the engine code in your VIN ? If it is a U, F, or D, then you have an early '65 model, AKA '64-1/2. Any other engine code & it is a '65 model. The K code is the only engine which carried over. from early to late production & I'm assuming yours does not have this code. Dean

We know from his post the car is not an early car.

The consecutive unit number is 262032 which puts it a few days after Ford restarted production after the shutdown and conversion to alternator cars. After the shutdown Ford skipped consecutive unit numbers at Dearborn to 250000. This is an easy way to determine if a Mustang is an early car or a later car at Dearborn. for San Jose the unit numbers restarted at 125000.

Adjustable passenger seat?
Gas cap with cable?
Those are couple things I can think of. You've definitely got a crossover car which is cool.

Part of the fun owning these cars is researching them. You learn things you didnt know about your particular year/model Mustang. I didnt know that in 65 a dome light was optional, my car doesnt have one.

After 50+ years and an unknown number of owners, who knows what is original and not original on my car.

I think that under my hood is mostly original parts. The PO is an automotive machinist and rebuilt the engine in 06. He says it has the original block, heads, manifolds, carb and tranny. Radiator appears to be original or period correct.

Im happy with it so far.
