i currently have a 12 bolt posi with 2.93s out of a 1971 riviera. i'm looking for a gear set that will fit this carrier. something more suitable for the strip. the 2.93s are geared too much for the high way for me.
If I remember right, you can go up to 3.23:1 with that carrier, gears from '71-'75 should fit. Hope someone else can help confirm this. Devon
