Trying to set up a 10 bolt rear for a friend...having troubles. Any help appreciated. Here is what I got. 10 bolt posi - going from 3:23 to 3:73 - Richmon gears. Factory pinion shim was .037". I have tried differnt pinion depths and have gotten the best pattern with .038" pinion shim. I have .010" of backlash and pics of the pattern are below. They don't look to good to me, however any move I make gets much worst. Car will be street driven and dragged hard at track...auto nitrous small block car. Suggestions? Thanks!
