Never restored one in my garage, usually at my uncle's house. The garage gets cleaned regularly, I guess I have OCD.
Driver's rear floor pan. When I got the car it was just laid in there and had a few welds and they sealed her up with some good ol expanding foam. "Quality work in my opinion".
Drivers toe board had a replacement toe baord just laid right on top of it till I pried it out in 5 mins.
The best for last...The car has had quarters put on it and if you were to go to all that trouble why would you not replace the trunk fillers??
Coolest thing I found when cleaning out the interior
