Got any good tips for finding this car?

New one to me & that 1970 Hamtramck Registry.Do you have a broadcast sheet or any other paperwork from it?
No. I used to have a photocopy of the window sticker but it appears to have been lost over time. I pulled the back seat up after I bought the car from the original owner and there wasn't any build sheet. I just learned that some build sheets can be on top of the glove box. Don't know if that is true but I never looked there.
