Hot Rods Cragar / Keystone Style Center Caps?

I have 2 sets of old Keystone wheels, but only 3 center caps. The only time I ever see just the center caps for sale is on eBay, and people are out of their tree on the prices for decent ones. I can find "universal" caps with 2 and 3 bars on them, but I don't care for them at all.
So, my question is: Do they make "universal" center caps for the Keystone/Cragar type wheels without the bars on them?
I appreciate any help. Thanks
