15x7 American salt flats. 3.5” backspace front, 4” rear. 225/60 15’s f, 235/15’s rear. I had to center the body on the frame (it was maybe an inch off) to get everything to clear.
We have a large regional tire company, Les Schwab. One of his managers makes a point to carefully measure and order wheels for hot rods. Pretty much matches the price. And guaranteed fitment. Happy to mount the blue lines I got from Diamond back tires.
Slick deal, did a lot of rods, and often got the daily driver business as a by product.
He had to do a little touch up grinding inside the wheel to clear the calipers on the fronts. No charge. Great guy.
Don’t know if you can find a guy like that, but ask the street rod guys.
