0207 MOPP 02 Z FLOOR
The owner told me in advance that the car needed floors, and, boy, he wasn't kiddin'. With the interior removed, we could see how bad the floors really were.

Project Valiant Floor Pans Brake Fuel Lines
Before you get the torch out, or a cut-off wheel like we did, check underneath to see where the fuel and brake lines are. These need to be moved out of the way (or safer yet, completely removed from the car).

With the lines under the car moved, lay the floor pan (in this case, the rear pan) on the floor where it will be attached. Then, with a marker, trace its outside edge onto the old portion of the floor. Don't cut the floors out until you have replacements; you can't make a hole smaller.

Project Valiant Floor Pans Cut Old Floor
A cut-off wheel or a plasma cutter works nice for cutting the old floor away. Make sure you leave 11/42-31/44 inch below your mark so you have some metal to weld to. After the old floor is cut out, paint the exposed metal with Eastwood's Corroless Rust Stabilizer. Once done, grind all the old paint from the area to be welded.

Project Valiant Floor Pans Spot Weld
When welding the new pan in, make sure there are no gaps between the two pieces of metal. Then spot-weld your floor with the spots about an inch or so apart; make sure the pan is completely down. I like to use a screwdriver to apply pressure directly under the spot where I will be welding.

Project Valiant Floor Pans Weld Stitches
When you're sure the pan is where you want it, put a continuous weld around it, but don't keep welding in the same place. Weld small stitches about two inches long and move to different areas on the pan until you have completely welded the seam. This avoids getting the metal too hot and warping or developing holes.

Moving on to the front pan, we outline the new floor pan so we know where to cut. Again, remember to leave enough metal to weld to.

Project Valiant Floor Pans Frame
The factory floor pan is spot-welded to the frame and the outside edge. If you don't have a spot-weld cutter, you can either chisel the spot welds or grind them out.
