8.5 has straps & 7/16" headed bolts on pinion yoke to hold driveshaft in.
OEM 8.2 GTO 10 bolt uses U-bolts & nuts. '68-72 GTO T400 driveshaft will measure 55 3/8" center to center on the u-joints. In Turbo 400 short tailshaft '68-72 GTO & '71-72 bigoutput shaft Muncie, when 8.5 A-body 10 bolt rear is swapped in, oem driveshaft must be cut down to 54"-54 1/8" center to center. I stock & sell both...some folks want one with new R/E.  Eyeballing things...There are actually 3 different bolt in axle 8.5 A-body housings that will fit in a pre '72 A-body, & 5 different 8.5 corporate rear covers, identifying by either is not always the wisest.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
