gijonas,
Mate you have some big ones! I couldn't bring myself to cut up a car like that. Although, I also have no metal working experience, so thats probably why.
I dont mean to put a damper on your efforts, but have you checked the clearance with the door handle?
My door handle is about half of the recess in the door, but it doesn't matter because it sticks out from the door. Im a bit worried with yours because now, the door handle is recessed as well. Are you going to be able to get your hand in there?
Have you thought about glassing ove the handle, going shaved, or how about relocating the handle to the top, kind of like a Lamborghini Murcielago
OFF TOPIC, damn thats a nice car
