Hey everyone new to this site and new to Chevy truck builds. So I picked up a '51 3600 and I'm thinking of replacing the rearend with a more modern swap. The existing brakes are bad and the hubs are leaking fluid. I'm also not a fan of the gear ratio. So I was reading this link https://www.stovebolt.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=831208
I was wondering if anybody had a more specific answer on what rearend to purchase. I was looking for one that is pretty bolt and ride with little modifications. Would like to know what other issues are involved in the swap like driveshaft mods and such. Want to stick with drum brakes and 8 bolt lug. Looking for a 3:xxx ratio. I'm going to be taking some measurements this week like backplate to backplate,overall width/track of the rearend, axle tube diameter , and spring mount location. Is there anything else to measure? Any and all help is greatly appreciated. Thanks again.
