Please tell me what parts interchange between the 2.45/2.25 vice 2.71->up 8 1/4 axle

No nevermind man has nothing to do with what you said in this post

Ok. It's a totally confusing thread anyway. That was my mistake on the other thread. I should have looked closer and I would have known the 2.71 was included in the numerically lower gear carrier. My bad.
