Got the side intrusion bar out, spot weld drill and a bit of persuasion sorted it, about 2kgs itself.
Tidied everything up with some more pinch edging
Re mounted
Quiet happy with the way it turned out and quiet surprised the difference in weight when swinging the stripped door compared to the drivers doors whilst on the hinges.
Easy 5kg I reckon.
I reckon I could sort one in half a day now that I know what needs to be done and take my time.
