Well, just an update. I decided to take a break from the floor pan install and went ahead and took off the rear valance and drop the gas tank and filler tube. Altough the extensions looked good from the top the bottoms were a different story. The driver side was pretty much toast and the other had a decent size whole in it. I pushed on it and sure enough a huge chunk of quarter panel & filler popped out the other side. Gez this car was doped up (filler everywhere). But I will get the last laugh..
