Im replacing my staked in ujoints with new and just curious if anyone knows if the 430-11a universals are the correct number alot of the powertrain websites show this as the replacement for 84-89 300zx but turbo is not noted in the listing i did notice a writeup on z31.com states that replacement joints are only avlable for the turbo sizes not n/a. Anybody been here before ???? thanks phil:burnout:
