removing duster floor

I just did this a couple weeks ago basically I jacked the car up and set it perfectly level, get a good spot weld removal tool and air chisel and go to town, once all spot welds are removed and the floor is out you can clean up any bad areas with a good flap disc grinding disc check out my pics under "member restorations" "73 b3 340 duster pro touring build" theres pics there and I can send or post others I have. good luck
