Yes, American Muscle says they will be out of stock for another 2 weeks, and the same ones from wheelhq.com are also out of stock for weeks.
So for now looks like I will go with the caps that came with the rims, then see what I can find later. If you come across some that fit and look good, please advise.
Nixtang told me that their OEM Ford tri-bar pony caps did fit these rims, so I might order a set of those, but I'd much rather have chrome caps or spinners... The only option I have founf so far are the ones that screw in from the back, i.e. from
BRS but they cost $200 (including the pony center cap) and I don't want to spend that much. I'm sure they're nice, but...
Maybe I can modify the spinners I have now - seems that they just do not seat down far enough - perhaps some careful grinding around the edges would do the trick. I don't know...I'll have to take a closer look. [&:]
