RF (I have 4 others to list - lmk what you need). I'm assuming Skylark & GS are the same? Fit other years ('64?)? See pics. Idk much about where these rust. Only serious rot. maybe good one to cut up & use to fix another. I'm not familiar w/ prices on '65 stuff. Let's start w/$75/offer. Located near Baltimore. Don't want to ship. Can bring to to BG or BCA Nats. Have some other '65-67 stuff. Lmk what you need
