Small update, big progress.
I finally got the floor pan welded to the frame. It sounds simple enough, but the floor pan has a nice thick layer of German underbody sealer on it, and it all had to be ground back from the welded edge. A big mess. Then, to make it just a little more messy, I seam sealed the whole area. I forgot to get a pic, but I used a honey consistency seam sealer so I could really flow it into all the nooks and crannies. Trouble is I'm doing this upside down so I looked like I pigged out at the chocolate fountain...
Also got a jack point welded in, seen it the top part of this pic.
Anyway, here's a shot pre-sealer.
And a couple more of the rad area.
