I have a set of the Pantera East wheels that were manufactured by Boyd Coddington. pantera East had an exclusive contract for this style of wheel and they were only sold through Pantera East, not available from Coddington.
I have heard that Bobby initially wanted to sell the same wheel but Coddington declined. Somewhere along the line someone came up with the idea of rotating the center pentagram so the pentagram points were aimed at the two slots instead of the large opening, as on the original magnesium wheels. This change in design was enough to work around the exclusive contract Pantera East had, and thus Coddington was able to supply very similar wheels to Bobby. Or so the story goes.
this rotation of the center pentagram is very often not noticed, with many owners not even aware of the design change until pointed out by me at various events.
good luck in your search.
