2 15X8 wire wheels

I need 2 new or perfect wire wheels for my 57 Chev. I bought this set from a swap meet many years ago. They were on a corvette, hence a big offset. I made two work on the rear by narrowing the rear housing, but they won't work for the front of the '57. I want to keep the same wheels, so I need 2 15X8 with a standard offset. I cannot find a brand-name on the wheels I have, maybe McCleans? ( could someone tell me who made these wheels? ) These are 15X8, with 52 spokes and universal bolt pattern.
