When I bought the '66 FB I didn't get all of the parts for the car. I could have sworn that I had the driveshaft for this car, but after searching high and low it's nowhere to be found.

I did find a '67 289 C4 driveshaft and also the one from the '88 Mustang (5.0 donor car). As luck would have it, neither will work. The '67 shaft is to long by a couple inches and the '88 is too short by a couple inches.

Since I'm running the T5, I'm curious now if the missing '66 driveshaft would have fit either....

I thought you could re-use your driveshaft with a T5 swap?

Is a '66 shaft a couple inches shorter than a '67 shaft?

If I can source (locally) a 65-66 shaft, will it matter if it's from an Auto or Manual car?

I've use Inland Empire Driveshafts to make custom aluminum shafts before, but before I take that big $$$ plunge again, I'm curious what my options are.

Thanks,

Dave

1966 shafts range from 49.70 to 51.06, with the most common manual driveshafts are 50.78".

1967 shafts range from 46 19/32 (C6) to 51".

I used mine with the front yoke from the donor car. It required an asymetrical (?) u-joint, but it worked. It was, however, very tight. I had it shortened when I replaced the rear seal.
At the time I did the T-5 swap, the parts houses sold a "conversion yoke, no need to shorten your driveshaft", so I sprang for it. For like about $75 or so back in ca. 1994. Turned out to be just a shorter yoke than the '65, same length as the '83. So I sent it back, used the Fox one and found a joint to fit.
Anyway, it'll work.
Later,
Dennis

Too late... I already ordered a new Alum. shaft from Inland Empire yesterday. It's about a $100 more, but it includes the 1350 size rear joint I need and also the front yoke.

I've used Inland Empire a couple times in the past and their shafts are top quality and made and shipped on the day they're ordered.

Thanks anyway!
