Well it would scare you if you walked into some bodyshops. When I worked at a place that rebuilt wrecks and the aftermarket panels didn't line up we made them fit. 1/2 is quite a bit. But we used to pound stuff in with a two by 4 against the panel. Or you could mount the door up and stick a piece of wood in the door jamb at a point where it doesn't stick out and shut the door on the piece of wood and hopefully get the door shut enough for the latch to catch and twist that corner in using you feet or something. I don't know what to tell ya. I don't think cutting the door would be real fun either. Thats the problem with aftermarket parts. Always wonder what people would think if they walked in and saw some of the fitting.
