The front driver's door and rear door of my Defender 110 have rotted lower frame channels, but otherwise the doors are in serviceable condition, apart from some paint blistering where the door frames touch the aluminium door body. I'm intending to 'unroll' the aluminium at the bottom of the door, remove the lower channels and weld in new ones, to save me the considerable cost of replacing the doors, here in North America. Has anyone done this? If so, can you tell me how you got on, and can you give me any tips?
Thank-you.
