I've got the door off, got the panel (which I ordered 3 months ago from AH Schofield) and I think there is a problem. The image below has one edge of the panel flush with the corresponding edge of the door. To my uneducated eyes its approx 4mm shy of being a good fit:

Am I missing anything or is it just a bad panel? I will clarify, this is my first time auto welding...
