This is a USA well made H/D metal piece for the LH side  of all 64/66 Mustang Convertibles that show rust if car is seriously rusted and needs repair in the trunk area. There is only side (left)  for $30 shipped free.  Hard-to-find since mfg. quit making them to sell since item was a slow seller or in need. Needed more today than several years past. Listed years ago for 25 dollars as marked. Thanks for looking. Take care and GOD BLESS   VOTE  fordmanted2b2b
