I have a 8.5" 10 bolt rearend from an 81 camaro( I think) with 3.08 gears and I found a 1992 chevy caprec with a posi in it,it is also an 8.5" 10bolt but it seems really big and the bolt patern on the axle is a 5'' like on a chevy truck not a 4 3/4'' will this posi fit in my camaro rear end and gears or will it be different or what the caprec has like 2.58 or 2.73 gears or somthing around there
