Next get seats carpet out and take a look at floor rust that has not been seen in 40 years. Been so long wasn't really sure what was there cause from bottom of car a bunch of under coating spray bombed covered up the mess from below. Luckily I did a super half assed fiber glass patch and was able to easily pull them off the floor. Red primer area passenger's side rear foot well is a snow shovel buried in caulk to patch a big hole back there cause by a spot weld hole in rear wheel well allowed water to fill that area up. But hey I did stop all the water leaks decades ago kept it from being worse.
