Little bit of progress last night.  Spent some time removing about 20 lbs worth of tar paper and seam sealer from the floor panel, transmission tunnel, rear seat pan, rear fender tub, and trunk.  Something to help me see the seams in the sheet metal better, determine where my good metal is, as well as some mild lightweighting of the chassis.  I want a sub 3000 lb car.  Still have to do the front floor pans but have to get the dash and wiring harness out of my way first.

Here's about 1/4 of it.  Came off easily with a chisel and heat gun.
