Thanks for all your input. Based on the rivets, I'm guessing the VIN tag was added to this car. It has the unibody frame rails welded together with 2 X 2 box beam steel, the transmission has a manual valve body. I've assumed it was raced at some point in time. There is no door tag and I'd have to scrap a lot of paint to read the trunk lid or core support. Someone took a highly optioned car and dropped in a numbers matching 340/727/8.75 drive train. I can live with that. I was planning on building a nice driver.
It had a PA title. Not sure what they allow there?
