the updates are here. The car came out of walnut shell and glass beading fine (10hrs for $1400, I watched most of it)! So far at $50/hr, I am only a day and a 1/2 of shop labor (they had to take the rear end out and the K frame, etc, front suspension, brake lines, etc). All the floors are mint! firewall is mint. Frame rails are mint, all the numbers on the body show up nicely. Media blaster said mopar underbodys are way more complicated than a GM.
I had them take all the sound deadener out of the quarters and wheel wells. Walnut shells rock for that. That car had NO real B5 blue paint under it, it was all the dipping primer. It had only a hazing of rust underneath that turned out to be nothing.
They will now hand sand it and etch/primer it today. We have an agreement to just replace what is needed on the quarters without a full replacement. That is where the labor charges will start to roll in. Doing it with a TIG welder.
Excited and very nervous!!!!!!!!!!!!!!!!!!!!!!!! (the job they did on a 67 chevelle convert sitting next to my car was to die for, it was perfect perfect perfect for body fit and no defects when I looked down the sides, so I think things will turn out ok).
