64 -66 cuda rear seat latch handle screw
Got them at Tractor Supply. They were in little plastic bags and came 2 to the bag. The cap head is close but not exactly quite the same but close enough for me. The back seat is gonna be down I expect 100% of the time in the wagon and since the only thing that's going to be close to stock is the body, the only one I only one have to please is me!
EDIT: They are by Hillman # H883034 and should be available at Lowes as well since they carry Hillman
