Curse and a Blessing

I know it has been a long time but life can sometimes get in the way of progress.  I have once again started working.  The frame is complete, the motor is complete, the rear is complete, the transmission is complete.  What have I been waiting on?
I have been able to get enough parts to almost put things back together. For sake of time and room, I have decided to finish the underneath of the body and put the frame back on. Having a two car garage has not given me much room. The frame is outside, covered in heavy plastic, but hopefully won't be out there for long.  This is the motivation I need to get it married back to the body.

Identification Code under body

The curse: 50 year old Ziebart rustproofing is over 1/8 of an inch thick over the entire underbody. In the channels for the frame, it is over 1/4 of an inch! It has held up well but some moisture has snuck underneath a few spots.  Scraping and brushing is taking forever for every spot.

Trunk pan = toast

The blessing: 90% of the areas are solid and only have surface rust. Once the Ziebart is gone, undercoating will be easy.  Next task after this will be trying to find the body mounts with the "special" nuts that attach to the frame.

I know there are some rough spots but that is the trunk pan.  I will be cutting that out and replacing it as soon as I get everything cleaned up. Only 1 side is gone but it is easier just cutting the whole thing out and replacing it.
