Great story. I think it is pretty neat to hear of another triple black 67 L79 Chevelle. Dad has the same car, documented with the protecto plate. It's not numbers matching (it was a race car in the 70's) But it has been restored to its original colors.
The unfortunate thing for us is that the original owner is deceased and his widow wasn't around when he had it. I have talked to the other owners but they don't have any of the original pictures. Dads car had sidepipes installed by the dealer when it was new. I left the brackets welded to the frame when I redid it. It didn't seem right to remove what was left. I did grind off the remnants of the old tow bar it had. I kind of regret that now.
