Driveshaft length.....again.

Interesting info.......thanks.
I guess I should have given more info on my issue. I bought this car last summer with the 360/727/7 1/4 and car was originally a 273/904/7 1/4. Had a bad shake which turned out to be a unbalanced torque converter (non 360) Guy that put the 360 in was unaware of the externally balanced requirement. I had to remove the tranny to install the B&M flexplate at which time I noticed the tranny yoke was at about at its limit in the tranny. Seems it is ALMOST too long. There is no way it will go back in once I install the 8 1/4 rear. I only want to either find the correct length shaft or have mine shortened. I suspect someone has a correct,original 727 to 8 1/4 for a 108"wheelbase a body. I can guess what will work,just hoping somebody had the right length number.
