They are 5x4.75, with 4.75" of backspace. I am uncertain to what the backspace setup on a G-machine might be, but I know most bolt patterns would match up. Seems like the other set of Intros that sold were the same setup!

I have big plans for the blazer build from here on out, just need to sell these wheels to free up a little money. The frame is completely rebuilt from the firewall back with 2x3" tubing. The floor is stock for the most part, except for the tubs in the back.
