HPP wheel center cap alternatives?

[Ike Clanton]

The center hole is supposed to be 70.5 mm and I need something other than the stock center cap to clear my front hubs. Yes, LSC caps will work, but what if I wanted to buy something new?

Assuming they are long enough to clear the hubs, someone tell me why these wouldn't work.

Those slip in from behind - wheel/hub clearance is already super tight, I doubt they will work.

Hmmmm

Yeah, I had to scrape/sand goop off my wheel hubs for the HPPs to fully seat, even then I had to draw them up tight with the lug nuts. I put some grease on them so they still come off easy enough.
If you haven't gotten a good look at them, the OE caps just pop in from outside with little thin tabs on the cap. If you find some after-market like that, they will probably work, as long as they don't have any inner structure to interfere with our hubs like the HPP caps do.
