Torque Thrust Mag?

[peter carroll]

A few years back, I found 4 Torque Thrust mags in the junkyard and they were on one nasty 912. Anyway, these are quite hard to find with the Porsche 5 bolt wheel pattern, so I am happy to have them. For those who may not know, they are made by American Racing and are very popular with"HotRodders" and are often on old racing Mustangs.
My problem and question have to do with finding the duplex lugnuts needed to hold them on. I contacted a company who then contacted American Racing, and A.R. said they don't have them. Duplex lugnuts are the ones with a nut and shank built in to one with a washer. I think I need 14mm X 1.50 . I got some of these at a local "flaps" as you guys call them, however, the shank part of the nut doesn't fit through the wheel. And, no I do not want to have the wheel holes enlarged.
I believe I have seen a member car or two with the same wheels. A black V-8 comes to mind that needed a bit of work. Anyway, any info. would be appreciated. I have just finished restoring them, so I will add a pic. at a later date. Thanks, Pete Carroll
