Just a little bit of trivia.
5.3 chevy, 4l80e with fixed yoke, 99 semi float 8 lug gm rear and I'm still using the factory 55 drive shaft with the factory 55 yokes, shortend a little on each side of the carrier bearing. original size ujoints and carrier bearing. And the factory 55 spring saddles on the 99 rear original 55 springs. I only needed new center pin bolts to refresh the springs. and new spring perches for the 99 rear.

Gotta love how gm used what worked good and didn't change it.
