1960 rear end swap help
My stock 1960 C10 rear end apparently can't be upgraded to taller gears and posi. It is the drop out style (55T?) with 3.90 gears. Can someone tell what axle would make a good swap? I would like posi and keep the 6-lugs and would like to be able to upgrade to a ratio of 3.50:1 or so. Thanks for all your help.
