Original Parts Group, Inc. (OPGI) is a tremendous source for GM "A" and "G" body restoration and performance parts. Without their catalog, we'd never have finished the SS496 Chevelle! OPGI not only retails parts, but they also manufacture thousands of the parts they sell. Tony Genty took us through the OPGI booth at SEMA 2007 and showed us the new '64 and '65 Chevelle auto floor shifters, some new GTO headlight bezels, and much more.
