These were in the glove box of my 69 Grande when I bought it in 1985 and I have no idea what they are for. I had sold the car shortly after and it sat untouched for 20 yrs, when I bought it back all the parts were still where I left them in 1987. The large one is rubbery and has a number of C9ZB 652407 A W and has Fomoco insignia next to it with a circled IMC and a half diamond next to the C. The one side has rounded edges, a notch on each end and a round cutout on the right. The back is flat.
The other item looks like it should be wrapped around a harness with tape to hold the harness in place.
Any ideas?
