I have a 55 first series 3100 chevy truck and am planning to install a n early sixties C-10 6 lug rear end in order to get a high gear ratio. I don’t have the original rear end that came with the truck so I can’t use those original leaf spring perches. Where can I get some new perches to weld on the replacement rear end that I will be installing? Thanks in advance for the feedback and assistance.
