i picked up a 9in full setup for a gbody but when i went to bolt up the drive shaft to the u joint, the u joint and yoke are different sizes. I think its because the original rear was the small gm rear not the 8.5 in that was in the grand nationals and regals. do I have to change the driveshaft and u joint or what? any help would be great!
thanks,
tony
