mr popes a smart fellar, listen to him. i've cut up a lot of cars in my time but the fleetline and oldsmobiles are one of the tuffest to pull off. i do not believe you will be able to do this unless you've done many before. your dealing with a roof line that goes from windshield to rear bumper. your looking at 5k+ to have it done and you better be sure of who cuts it. most i've seen look bad. you can cut the front 1 1/2 and lean the post back without butchering the rear lines. a pie cut at the rear qrt window will let it fall this far without messing up the rear lines. good luck...your gonna need it.
