Rim Backspace Question
I have a 1970 GMC C-20 with rear leafs. It is droped 4-6 (spindles, cut coils and flip kit). I found some rims, but I dont know if they will fit. They are 18"x8.5". The website says the "back side"?? is 4.75, is this the backspacing? Will these fit? Thanks guys.

Re: Rim Backspace Question
4.75" is the backspacing, but I am no expert on fitment, there was a
wheel and tire fitment thread on here a while back, maybe it's in FAQ ![]()

Re: Rim Backspace Question
I got mine at GMC Pauls, part number 1181582. I think thry were $229. They are 73-87 spindles but still keeps the 8 lugs which I wanted. I had to change to 73-87 upper and lower balljoints and outer tierod ends. I dont think you have to change the lower ball joints but I did anyways. I also changed to 73-87 disc brake setup. Ill take pictures later tonight.
