1984 Hurst/Olds, '85-'87 442s, and '84-'87 Turbo Buicks got the 8.5" rear. The Olds cars had 3.73 gears, and the Turbo Buicks had 3.42s. Posi was optional on all rears.

If it's truly a G-body 8.5" rear, it should have two "fangs" on the lower part of the center section. Most likely, you found a 7 5/8" rear out of a Monte SS, which would have 3.73s in it. Again, the posi is optional, so make sure that it works before you pay for it.

Good luck with the new G-body!
