Truck rally wheel questions

[71-C10]

I have a set of truck rally wheels on my '71 that came off of a 75 or 76 . They have center caps that mount with screws from the back side of the wheel. Over time the center caps have pitted, and the chrome has started flaking off. I'm in the process of painting the wheels, and the trim rings are in perfect shape. I can't find exact replacement center caps, so I contacted a chrome shop to see what restoring the center caps would cost. After reviewing photos they told me $125 for each center cap. Total $500, free shipping both ways. I'm looking at all of my options. Will the center caps that bolt from the front work on my wheels? If not, I may just put corvette rallys on it. My personal preference is GM rally wheels for my truck. Anything else will not work for me.
