I inherited a cool set of magnisium wheels from a good friend. They appear to be made for Corvette disc brakes, so they are probably from 1965 or so. They are feather light and have no markings at all on them. They are 15 x 6 and 15 x 7 in size. Did American wheels have markings on them from the manufacturer?

If you take a Scotchbrite pad, or wire brush, and gently scrub the back side of the spokes you should find a casting date and maybe even a part no.#. I want to say that mine have a 1965 casting date on the the back side of the spokes. You've got to look very closely because the numbers are cast very shallow but they should be there. As bitchin' as they look and don't hold me to this . . . . . .but I'm pretty sure that those particular wheels you have would require a spacer for disc brake caliber clearance. I agree with Bill though, they would be so tough on a '66 L-72 Coupe stripped-down!
