FIRST, always wear safety glasses or preferrably a face shield, a dust mask and some good gloves. Now to begin...
The trunk floor pan and the cockpit floors were perforated with rust and required replacement. With the car on jack-stands, I began by removing the fuel tank, fuel pump and fuel lines all the way to the engine compartment. DO NOT GRIND AROUND FUEL...ONE SPARK AND YOU ARE TOAST !
Next, I cut through the rusted metal floor pans with a side grinder taking care not to cut any of the support beams beneath and around the outer edges. Next, remove the welded areas by drilling a hole at each spotweld and using a pneumatic chisel or hammer and chisel, seperate the floor from the frame. These floors were so rusty that portions of the supports were also compromised. It will be necessary to repair these supports prior to welding the new floor pans in place. The frame should be cleaned with a grinder or wire brush to remove all rust. You cannot weld rusty metal.
Before removing the trunk floor pan, take a good look at the new one. Notice how it is made and where and to what extent you should cut the existing floor. There is virtually no support under this section of floor. It is only supported around the edges. As with the cockpit floors, clean the edges to be welded with a grinder or wire brush to remove all rust.
Now you are ready to weld in the new floor pans.
Later,
