Here are a pair of factory-original fender skirts from a 1949 Mercury (are NOT reproduction or aftermarket).  May also fit '50 Mercury, but the buyer will need to check on that.  The part number (stamped on the lower edge) of the driver's-side fender skirt is 8L-7327989 and the passenger-side 8L-7327988.  The driver's-side one is in excellent undamaged condition, straight and dent-free and with no rust.  The passenger-side one is also rust-free, and is straight overall, but has a small shallow ding (under one inch wide) just above the bottom edge, and a very shallow and narrow dent (a crease) that is several inches long, also just above the bottom edge.  But both of these flaws would be easy to fix prior to applying new paint. On both fender skirts, all mounting clamps, braces and rivets, etc. are there and undamaged.  The rubber seals on both fender skirts will need to be replaced.  Buyer to pay $35 shipping in the US.  International buyers, please inquire for a shipping quote.
