Ohhhh!!! not put anything up on here for a while. I put a request for rear doors up a litle while a go, many thanks for the replies and there were a couple of tempting offers, but like a masochist I decided to have a go at fixing them myself....idiot.
The drivers side door was first, as this was the "better" of the two, and was rotten at the bottom, both on the outer panel and inner panel and didn't prove to be too much of a problem. The passenger side was another story, I knew the bottom was constructed of expanding foam and filler.....but until I removed the glass, I wasn't aware that the bottom of the area where the glass sits was also constructed of (wet) expanded foam and filler.
I managed to repair the top of the main skin, but suffered some warpage to the outer skin,
so tried a different method af attack on the bottom repair, I made up a panel and added a stepped flange, so that this sat behind the original door skin, I then used the punch on the joggler to create a line of holes on the original panel and then "button" welded the panel in place. This was then lead-loaded before a skim of filler was added.
I have spent the last week, filling, sanding filling sanding...you know the score.
I finally managed to get some paint on today, and while the doors are not perfect, I don't think that they are bad for a chef!!!
The line just below the window on the passenger side is not as sharp as it should be.
And yes I know I have forgot a pair of hinge holes lol
