Interior question --- 77 k5- I can\'t find the piece of trim that holds the looked everywhere..where do I get the piece of trim that holds the carpet down towards the rear of the door. This is not the long piece, but is a curved aluminum piece that mounts near the seatbelts to hold the carpet down. I have a 77 k5. I checked all the usual places...chevy duty, lmc, golden state, etc. If you have a used pair you'd like to sell me I would be interested also.
