RE: Concept Production changes...
I know a company here in Mexico that used to produce the frames for those AZtec models.... a friend of mine that's working with them told me it was a huge disappointment since they decide to pull back the project while ago.
IN other news... for work I visited a crank manufacturer down the center of Mexico, they produce the crank for the Charger and seems they're bidding for the Challenger.... hope I can get some info from him.
