So I am on my first build of a pre 1960s vehicle and I am working on a 1949 Chevy 3100. I have changed my front suspension to modern day and its track width is 56". I am going to the junk yard today to pull a GMC Jimmy 10 bolt that measures 58". Online it looks like only a 70s Ford Maverick measures 56" for a rear end and those aren't piled out in the junk yard. I'm thinking I will have to add 1" spacers to the front rotors and then i am streamlined. I am hoping someone has done a similar build and can help me with what size rims/tires they went with. 16x6" smoothies, 4" backspace?
