I've had an aircooled sat in my driveway since last year which needs a bit of work doing to it.
Rotten bits:
bottom of both doors,
top of drivers wing,
rear drivers arch,
rear tail light section,
section below windscreen,
both wing repeater sections.
The plus sides are that the sills and floor are solid and the rest of the arches are remarkablely intact.
I started welding a few weeks ago. I managed to source a few panels that I was able to cut from a 126 (the donor was in much worse condition than mine, but thankfully in different areas)
I cut out the section surrounding the rear tail light and have welded in its replacement.
I think I got it pretty close, but it will still require a little filling to make it perfect. I'm trying out lead fill on this section as it is an area prone to water ingress.
I had a replacement door ready to use, but it doesn't fit!!!
It bolts in ok, but sags far too much and when shut, leaves a panel gap that is tapered, making either the car or the door look squint. I attempted every trick I knew to bring it into line, but in the end I employed the rather brutal tactic of cutting the bottom of the good door and welding into onto the original.


There is a reinforced section of the door that the hinges are welded onto. By leaving that intact, the only changes I made were to the skin, so when everything was tacked in place and offered up, it still fitted the same.
welded it together and the next step is to apply some filler to the weld line area.
For the mean time the door is sat in our spare bedroom to dry it out a bit before I give the innards a good rustproofing and apply some paint. My Girlfriend hasn't noticed that the door is in there....yet!
Door will be painted within the week to verde brilliante (colour of the inside of the door)
I already have tha paint in the garage from an ebay company who mix to code or pantone (let me know if you need their details) so it's rolling forward, slowley!
