1966 Dart, my new driver

That interior looks like it could have come out of a recent car. Some of the old cars can get away with modded, or completely different interiors, and to me, the A bodies are among them. Yours shows it.

Maybe a few horiz orange or silver bars across that black grill, would be the only thing I'd add. Otherwise, as we kids said growing up in Detroit in the early 70's, "BADNESS!"
