Okay. Last year I swapped a 4.3 torsen into my 1.6 & changed the Axle bearings to 99's (B455-33-047C & D) in the retained 1.6 uprights.
In prepping for the 25hr I am changing the Axle bearings again. The shop I'm using to press them in says the bore where the bearing seat is out of round, which will lead to premature failure. So, I want to get a new set of uprights from Mazdaspeed ($$$), they come complete with new axle bearings & seals.
My question is this: Since I cannot use a 99 upright will 99 axles work in a 1.6 Axle bearing (B455-33-047A & B)? The only difference in the part numbers is the A, B, C or D...
