what would happen if i did this?
 

i know your not supposed to mix a ring and pinion gear and they come as match set> but what would happen if i do? i know an auto rear end is 3.9 with a 43 tooth ring gear and a manual is 4.1 im guessing the ring gear is 41 and the pinion 10 this would make the 4.1. if im correct on the gears for a manual then i could make a 4.3 by mixing the auto ring gear and manual pinion. im just wondering what would happen if i mixed them up instead of buying a match set thats 4.3

two things.
1) the teeth wont match up
2) pee would come out of your butt

^^LOL and yea exactly

thats what i thought but i just wanted to arouse my curiosity because i had always been told they have to be a match set but wanted to know what would happn if you mix them thanks guys for the input i'll just my the 4.3 gears from rx7.com
