There are a few cars in Mn we dont know about. I have not seen them but there is a guy in MN that has (2) 70 Stage 1 auto convertibles and 3 65 Gran Sports convertibles and nobody on the board knows him. I guess he owns some big company not related to cars and has guys that restore cars for him. I think he is working on a 50-something Buick convertible now. The guy that polishes my stainless works for him. There is also another guy up north that has a Stage 1 hardtop.
Bart, protecto plate is from the car on eBay? If so she's a 455. TR code. Vin for all '71 cars was the same regardless of engine displacement.
