I thought it was too wide, i don't care if it's 5 or 6 lug, turns out that my uncle put a nova rear end in his '46, and it fit like a glove he said. Even the spring perches fit i guess. I think i have one of those so i might try that. First thing i have to do is get the front brakes put back together though. I'm going to adapt discs to it i think.
