Today I was able to get the seats, the last of the carpet, and the last of the trim removed.
Getting the old seat belts removed took the most energy. A little "bolt and nut buster" spray really helped loosen the nuts underneath the car. I think the old seat belts hold that musty odor more than anything else does.
I know the floorboards and everything else looks rusted, but it really is old glue that is making the metal look so bad.
Frodo the Frenchie is not too happy with the slippery metal. If we get some warm weather, he should have something to grip. Before anything goes back in, I will remove and recover the dash. I am also going to give the floors some fresh paint for protection.
