Boy I just scored big!!! I found a 67-72 3/4 ton gmc In a local yard with the H052 axle with 4.10 gears. looks like brand new on the inside & very little slack ( you want some ). All I'll have to do is replace the pinion seal & I'm good to go. this is going to be a really big improvement in my 50 3800. now that i have my broken speedo needle fixed & cable greased i realize i was going alot faster than i thought i was! now that i actually know that i'm going 50-55 it isn't near as loud. the 4.10s will be way better than the 5.14s going down the road & i'll still be able to pull anything i want too.
