Hey all, new here. I'm looking for any and all helpful suggestions. Over the weekend, I broke my pinion on my borg warner in my 89 firebird LT1 running CMC2. I had been running a 3.45 gear but was considering going to a 10 bolt and a 3.90.
Any suggestions regarding the rear end and differential is appreciated. |

7.29.1 should allow the update/backdate across the generation. Otherwise, 3rd gens have to run adapters to accomplish it. A 4th gen housing is cheaper then a set of adapters, it lessens the weigh gain vs. adapters, and it allows the use of cheaper OEM wheels. Based on "spirit of the rules" arguments, this should fly.
