Help with Center Caps

[Gordonr1973]

Hi,

I need help finding some center caps for my old style slots....

I went to a rim wholesaler yesterday with one of my rims to get it measured and to see what they had.

The old dude there said my rims were likely "Helibrand" from 1976 and the closest center caps he had were 2.925 (too small) and 3.15 (too big)

I measured the rims tonight and the outside face hole diameter is 3 1/8" (3.13)

The inside face hole diameter is 3 5/8" (3.63)

I looked on ebay...no luck...any suggestions??

Thanks!
