I cut 6" from A pillars and around 9" in the rear. Just kept cutting until the lines looked good. The rear window has moved forward about six inches. when i got the car i removed the roof skin as it had been jumped on and caved in so it was pretty badly rusted out. had a spare roof off a 4 door.
i like it! at least you know how to work on your ride. i cant weld shit! it looks good though! keep us posted!
