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

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.
Like when I said there is alote misleading info the beginning of this one was one of the many. I’ve posted want ads for the suregrip I need about everywhere I k is what I need to do and look at info about it is in the past
