Odd driveshaft
I bought a driveshaft from a guy who restored a '69 Boss 302 and it was left over in the parts he got with it. He said it was out of an '68 Mustang. I just switched to a T5 setup and the front yoke works fine but the rear on didn't have the caps on the 2 ends that go in the yoke of the rearend.
I went to the local parts store and bought a ujoint for an '68 Mustang. Well it won't fit in the shaft holes on the end. I took it back and brought the ujoint that was on the shaft and couldn't match it up. Now looking at the front yoke it has 2 sizes of caps, one size for the shaft caps and 1 size for the yoke. I remember someone either saying something about a sie change and or having to buy 2 ujoints to get it to work like this. I can't find or remember where I saw/heard it. Has anyone run into this and what they did?
Thanks

RE: Odd driveshaft
Sounds like at least one end has a "hybrid" u-joint, these are available to adapt things together that don't go together. 
You probably wont find them at AutoZone or even NAPA, but a driveline shop can help, and they will be familiar with them.
If you knew what to buy, a hybrid joint would work for the rear as well. (could it be the same as the front joint that came with the shaft? If so, you have a part number that might work at most parts stores)
In short, you have a couple of solutions to your problem. You can have the ends of the shaft changed to match your yokes, (couple hundred $$) or find the right hybrids, (lots cheaper, not necessarily the best solution, but a good and viable solution none the less).
I think I would go the hybrid route if the length of the shaft does not need changing.

RE: Odd driveshaft
Looks like both ends have the same sie on the shaft. The front has the full u-joint with the yoke attached the rear was missing the caps for the rearend. Unfortunately the ID for the u-joint is smaller and the caps for the correct u-joint don't fit.[:@]
I guess I'll try to find a local driveshaft shop on Monday to see what they can do. I had high hopes that I could test drive the car while it is warm this weekend.[&o]
