Here are the rear window base moldings from a '60 Lincoln Continental Mark V.  May also be correct for the '69 Mark V, but the buyer will need to check on that.   Are in "driver" condition with some pitting in the chrome, but no cracks and no rot to the base metal.  Would also make excellent cores for new chrome.  All mounting studs are intact.  Buyer to pay $22 shipping in the US.  International buyers, please inquire for a shipping quote.
