Is there a difference between driveshafts for a 6-cylinder and 8-cylinder 1968 and 1967 Mustang? How about between manual and automatic?

why have a big heavy v8 shaft turning a 7.25 inch rear? you can upgrde to a v8 shaft and they make u joints to do it but. the rear wont be able to hold it. if you build a six or put in an eight i recommend upgrading , maybe aluminum too. but yes there is a difference. lengh diameter everything

I'm pretty sure there's no weight difference between the I6 and V8 shafts. I'm also fairly sure the shaft out of an I6 with a C4 is exactly the same as the V8 with a C4. The manual trans's shaft is different, I think.

How that for an utterly uncertain set of answers?
