I alternate between thinking that I've made a huge mistake, and being pleased with the progress...
Step 1 - Get rollcage installed (Competition Cages did a GREAT job on this one!)
Step 2 - Discover rust in floor (note that these should have been done in the other order)
Step 3 - Get bummed out
Step 4 - Get pissed off and do this...

Step 5 - Get a new piece of tin and cross brace with seat mount from the VW counter (surprisingly affordable!)
Step 6 - Voila - the new bits will be stitched in with the MIG from both the top and the bottom

We've also been grinding undercoating and tar out of the tub thanks in large part to loan of a SnapOn Crud Thug from Jon Bonforte back in my old stompin' ground in Washington State. If you've never seen one of these things work, you need to check it out.
