1966 Dart GT, 273/4, 4 speed registry.
I have a local friend that's had 2 66 GT Coupes with factory 273/4 barrel/4speeds. One was light blue and one was red. I doubt he still has the info/vin about them though, it was 30 years ago. Red one was cut up/had rusty rear quarters, blue one was t-boned and eventually fixed/probably still out there somewhere.
