when i get home tonight, i will post some pics i have of the evolution of the mustang, some of the sketches resemble the 64 t-bird, one of the first prototypes was in 62, a two seater w/ rear mounted V4 engine. there was another one with what looks like hide-a-way lights. it is in a 1970 ford magazine that i saved, i keep it sealed in a freezer bag. there is some bizzaro Ford stuff in it.
