******REVISED TOPIC*****Auto -vs- 4 speed Driveshaft and yolk?
Does anyone know the measurements for these driveshaft? My '68 is a factory 4 speed car, but I just took out a TH350. I'm getting ready to stab a Muncie back in it and I'm wondering if the driveshat I have will fit. The one that's in there measures about 31 inches from longest point on each end.

Scott, I don't think you will have a problem. Going back to one of my Camaro's I did an auto (TH350)to manual with a M-20. There was not any length difference in the driveshaft or yoke. I didn't change anything. One of the above posts says the TH 400 yoke is the same as a muncie, I'm pretty sure that is wrong. It is the same as the Borg Warner T-10 though. Different spline and bigger around. I don't see any problems with the length or anything with what you're trying to do. Chevy was great about the interchangeability of parts. Hope I'm right on that one!

As others said, driveshaft length between TH350 and Muncie manual trannies are the same length...

OK - I planned on trying to use the same driveshaft, but the new yolk for the muncie is a lot bigger than the one for the TH350 I just took out and of course it will not mate to the U-joint. Is there any way I can make this work without having to buy a new driveshaft?
I was hoping to complete the installation tonight or tommorrow.
Thanks.
