Haven't seen that one before, but there's a person on Facebook who's doing the same thing with a 68 Chrysler - making a 4 door hardtop into a 2 door hardtop, but retaining the 4 door's standard rear quarter roof line rather than the reverse window line. It's looking quite cool! Remove all the spaces in the link and then paste into your browser. Otherwise it won't display on this page.
