In the end it was actually cheaper to swap to the 8.8 than it was to build the 7.5 with tlok, 3.73's, and LPW girdle.
+1, I have a friend local to me I know personally that put a T-Lok and gears in his 7.5 and had issues with it making noises, etc. Had it rebuilt again, same issue. He has spent with parts and labor close to $750 or so and it still isn't right or as strong as the 8.8 stock.
