Got some time to work on the Panama last night after the kids were in bed. I removed all the items from the trunk, which consisted of whatever parts the previous owner had removed. Lots of trim, the door panels (they need to be replaced), seat belts, and some other miscellaneous stuff. I put all the stuff on some shelf space that I'm reserving for the car, and will label and organize all of it.
The gas tank has been leaking slowly but steadily. It stinks up the garage and drives my wife nuts, so dropping the tank was next on my list after stripping the interior.
The fuel line thankfully disconnected without any issues. I removed one of the clamps on the flexible breather hose and took the hose off one end, so that I could get it past the leaf spring. The strap bolts also didn't give me any issues.
The leak is coming from around the drain plug "collar". The plug appears to be rusted in place (probably cast iron instead of brass), and the collar has broken loose from the tank. It spins around with no seal.
The rest of the tank appears to be in good condition(the pictures make it look worse than it actually is). The entire bottom of it is coated in some sort of thick undercoating that is beginning to flake off. I'll probably remove all that and repaint the tank.
