Wtb: 1971 dart gt
Dang, don't know how I missed this one!!!
Yes, they sure as heck did make GT's in 1971. I have two, #65 and #69 in the registry.
As Dan pointed out, original 1970 or 1971 GT's will have the "A65" package listed on the fender tag and buildsheet. '71's have a one year only rocker badge, as well as a slightly different interior pattern. Bucket seats were part of the package, most had consoles.
I found both of mine local to me in under a year. This is my EL5 GT, with the rocker trim...
