I was able to use a sharp chisel and a hammer to break up the stuff. It was a little easier in my case because some idiot (ok... an idiot prior to me) tried to jack the car from the floor pan. When the floor pan dented upwards it cracked the stuff so at least I had a good starting point
The stuff some people do, right?
You know there is a bright side to being foolish. Sometimes I just think about all the great experiences I would've missed out on if I had known better. The crap in the bottom of the floorboard. Replacing the headliner. Being able to start the car without a screwdriver. Fixing the shifting problems. Getting the CIS sorted out. Hunting down electrical gremlins. Taking care of some rust before it became a real problem. Yea... good times.
