Here are an Eagle SX-4 and a two-door Concord I found in a backyard collection of junk cars not far from where I live. There likely are lots more like these if people could find them. They were pretty well buried in vegetation.

SX/4 sport mirrors : )
Did you have to cut away the vegetation so you could see them? You must have felt like Indiana Jones searching for ancient treasures!
