Hi to all;
I restored the engine and trans. on a 66 Shelby (6S502), in 1998. The car was very original, with one repaint, never any rust, or accidents. In fact, the car was sold here, in my hometown in southern Oregon, and I remember seeing it when I was a kid! It was a one-owner car until 1997. It now belongs to one of my best friends. When I restored the engine, it had a blue alternator pulley and fan. Of course, the rest of the drivetrain was all original.
Hope this helps!
