If a 5 lug 9.5” rear axle pops up I’ll grab it but I am not going on a treasure hunt to find one.
I have a 3.73 posi 14bolt 9.5 rear out of a 90 454SS .... $600...I was going to use it in my 94 shortbed 4.3,was going to V8 it for a tow rig,but got a 99 tahoe now for tow rig..so i wont be using it..

I wont have it long once someone see's it..,Hard to find..limited produced..I have it on CL and soon it will go on ebay...


Get a posi unit out of a 91-96 caprice or roadmaster...90% of wagons had posi...the spid lable in inside the tailgate on the right side. G80 is posi..

They are the old clutch type and will bolt right in. You need 2 wheels pulling that BB
