This may be a crazy question but what I'm needing to know is if it's possible to change the quarter glass on a 67 galaxie 500 (ltd) from the short (small) style to the long style like on a fastback, I've have a guy wanting a frame off resto on his 67 but he wants to change the quarter glass from the short to the long so what I need to know is if it can be done & how hard would it be to do it, any input would be appreciated, thanks in advance
