Front wheel with more than 2 1/4" backspace

I have a 71 with a 28 in. frt tire with 1 3/4 BS. Bogart,no clearance problems.Do you know anyone that has a 2.25 BS rim that you can try,it should work even with a 28 in.tire.If not somethings not right on how far the rotor/caliper sets outward...gsa612

G/SA I wish I knew your name. Your example made me dig deeper. We use the same inner fender well (1971 and 1980 are the same). So it is essentially the same car. I removed the wheel and made a bunch of measurements. I thought I have a 3.5" wide wheel. It is 4.5" wheel. So if I buy a 3.5" wheel that moves the center of the wheel in 0.5" right there. On top of this my Weld Wheel is a 1 7/16" backspace, not 1.75" like I thought. So I think your 3.5" wheel with 1.75" backspace moves the tire in about 13/16". I think that works even on paper. Thanks for taking the time to reply and get me off my behind. Ray
By the way I use Strange brakes. The rotors space the wheel out about 1/4"

Ray, the names Bond.. James Bond..LOL.Anyway its John.Looks like you got the BS deal figured out.How are your lights with the 26' tire,If you used a 28' it may be a couple of ticks faster with the extra rollout...gsa612
