So I got a 8.5 posi but its for a f body(nova, firebird) could I find an A body 8.5 peg leg and swap out the carrier ? or should I keep looking for an A body posi
You're talking about one that you can put in a 68 or are you trying to put a later diff in a 67?
As you know, the 8.5" to fit 68 to 72 A body likely only came in 72 Chevelles as determined by a thread here a while back. (At least I am hoping you recall that, it seems to me you where in on that one) Anyway, yes, you can just put the guts you have into a Chevelle 8.5" housing.

From what I know, it's a bolt in, just a touch wider as I'm sure you are aware.
Only issue maybe the yoke on the diff. I suspect your 67 has outside snap rings, the 72 diff will have inside snap rings on the U-joint from what I recall. Simple cure with a conversion U-joint.

The 8.5 r&p set won't fit, but an 8.5 posi unit can be used in an 8.2 rear. We used to use them before Eaton released the newer 8.2 units, because the 8.5 units were much easy to find. Later, Eric

I'll have to look into this one. I know that the ring gear bolts are not the same size. The 8.2 uses 3/8 bolts and the 8.5 uses 7/16 bolts. I haven't checked on any of the other dimentions.

BGH, We used a thin wall DOM tubing from Victory Tube Products to make sleeves for the ring gear bolts. I think the only other mod required was some of the castings needed to cleaned up for clearance on the passenger side of the case. I will see if we still have one of the old setups on the rack and post a picture. Later, Eric
