Dave-The wheels may fit, but tha backspacing may not be what you need. You might check out PS Engineering wheels in California. Phil Schmidt makes the Halibrand style in bolt-on and pin drive, with whatever offset you need. I have a set on my 40, and they are excellent wheels. Mine are bolt-on, as I don't trust the knock-offs for the street. I saw a wired knock-off loosen and allow the wheel to come off on a freshly restored Comp Cobra at a Shelby track event a number of years ago, and that convinced me it wasn't worth the worry.
