Looking For Machine Shop With Large Tap & Dye

[illz]

I have no idea where to start my search, so I'm hoping someone here can point me in the right direction. I have a set of RH Evo wheels that have an aluminum center cap. The center cap has 2 alan-head screws that are concealed by a large aluminum nut, which screws onto some aluminum threading, 2" in diameter. A long time ago, Isaac, that dirty Elite bastard , cross-threaded one of the center caps and nuts. RacingHart distributors want $90 for the center cap assembly, and I don't want to give it to them.

Does anyone know where or what machine shop might have a 2" diameter tap and dye to rethread the center cap and nut? JET do you have any ideas?

Any help is appreciated, I have no problem spending an hour or two on the phone calling around, but I don't know where to start.

Thanks in advance
