Dana 60
Ive ran the same Dana under 5 different cars and used everthing from a 4.11 to a 6.17. I guess You call it a carrier type. Ive used all Richmond gears and they all set up within a couple thousands of each other. I just bought a new pinion bearing for every new gear set and left them on. 2nd I set mine up putting the shims behind the race, not behind the pinion bearing as some do. Swapped out ratios by just installing the old pinion, and the carrier bearings were even close enough without changing side shims. No failures, even Katrina couldnt kill it. Good Luck :lol: P.S. If You have a 4 series chunk, I dont think You will be able to use the 3.73s, if You have a 3 series, You may or may not need a spacer for the 4.11s :wink:
