Everybody think hard

[bb427stang]

I decided to change the look of the Mustang with new tires and wheels and now have a problem trying to find center caps for the right look. The stock bullet push-on caps are atrocious but the center bore is 3.125 and I can't find what I'm looking for. I'm going for the old Halibrand, s/s look, so I need some flat faced caps that stick out from the wheel as little as possible. I need somehting like the bases in this pic that will go behind the wheel, around the lug nuts, and up through the bore (no, not with the spinners). I remember seeing them in the old days, but don't know who (if anyone) has them now.

I'm going to do what we did in the 60's until I find them... no cap on the rear, and a chrome grease cap on the front hub. I sold the roadster, so it's back on this one.... more hp, different look.
Help!
