Biggest problem with a chop on a car like this, aside from the obvious metal work, is the glass. Side glass isn't so hard, it is the windshield and rear window that is the problem. To have custom glass made, or a stock windshield cut down is sometimes very expensive. Finding shops capable of doing it can be a challenge also.

Before I would start cutting I would research who will do this for you, and how much it will cost.
