I've got a build sheet which I thought I pulled from my sister Eileen's 1969 LM1 Camaro. I don't randomly collect these things but with a Baltimore call out, Rich Pern has me scratching my head. I don't understand how this got strapped to the bottom of the seat of my sister's Camaro. She is the second owner, and we know the car was sold out of Coupe Chevrolet. I would appreciate any help understanding what kind of car this is supposed to go with.
