Tack welded in the patches and restored the tow hook!  Thanks for the donor items Danny Quigley!  I strengthened the tow plate by adding a plate to the back so it is now double thickness - because the donor tow plate had been folded from a rear ender I think.  You can see that sort of in the paint there was a somewhat diagonal fold line.  

Now I can really get towed out of the swamp.  ?.  Or onto a race track in reverse?  

And here are the four newest patches - not completely welded up but tacking is done and all surfaces flat/gaps ok.  There are two other round patches that are finished up.  I tried to Tig in ONCE and blew right through. I am a newbie.....  Mig is waaaay easier and very little to no distortion.  Just a harder and more metal type of cleanup.  I am using ESAB 023 wire and it is designed for auto body - it is a bit softer and more tolerant to back yard mechanics I think.   More pics to come when I attach the tow hitch below.  I know a new trunk insert is available but this is waaaay more fun.  Can't wait to the day there is some nice fresh paint / bed liner and a fresh Pirelli Centurato all around!

Next I will tackle the rear panel rust by the left license plate light.  Same idea - cut out the rust and weld in a donor from Danny!  

And here she is just about finished up for the painter/undercoat.  Thanks again to Coloincaalpine for the donor hook!
