If a 4 door is what ya got, go with it...the posted pics look kick but ! A friend of mine did a 69 four door Chevelle, shaved back handles, two tone paint, it looks really nice... For a Chevelle...lol
If you shave the Handles and use a Remote with Battery, make one Door a hidden Cable release! don't get locked out!
Looks incredible, but that's a lotta work. At a Goodguys show I once saw a chopped '69 Mustang sports roof. It was chopped so well you have to stare at it a while to be sure what you were looking at. Very impressive.
