Seat belt hardware

Same bolts all the way thru the 80s. You can even pull em from an FMJ body. Shank length varies from vehicle type to type, but they should all be same thread, and bolt head. I think 3/4" bolt head, but i could be mistaken.

My 88 daytona shelby i think even used the same bolts. I believe they were the only thing that was SAE on that car.
