uwbuurman: I have a few, not too good picture. First, I made a pretty fast "looks like everything okay" work, to go to a holiday. I drilled the tail panel, then screwed it into a thick oak board inside, I hooked with wire rope and pulled it out with a big gas.

The end result was not that bad.

The left side popped out to its original shape.

Then plastered the tail panel with a lot of fillers. It is good for a year. On the last autumn I started the work. Need some work on the front windscreen frame, a minor work on the right side floor panel, and here we are.
Jeroen: thanks, I did a lot of work on the car, and its just a short post here.
The pics in time order after I pulled out the tail panel. I said, that is a lot of filler.
It looks fine from a distance....
And after one year...wow it doesn't looks that great, time to work
of course, when I need a tailpanel, I can't find, so using an old one. After some care, I sandblasted the whole panel
hmm looks fine to me
...and with epoxi primered
Thats the big story. Not too much pics, but of course I need to smooth the boot floor and there are still a few things that were much shorter in time to describe than to do it.
