Got much of our Cuda in boxes and have a few odds and ends left on the bottom of a box. Any idea what these are from? I'm wondering if the spring is part of a slapstick set-up, but can't see how or where it would fit. The seat hinge cover says 9825376RH on the back. I don't know even if it is a Mopar piece, but there were a couple of A-body Barracuda pieces in the boxes.
