Floor Pan Replacement
I just stripped my 87 5.0 LX last weekend to start restoration. Both floor pans are deteriorated. The passenger side is the worst, it has a 1 inch diameter hole, and the seam on the one edge is not connected to the brace. The driver side doesn't have any holes and the seams are in tact, but you can tell by pushing on it that it is weak.
The heater core is disconnected so I am assuming alot of the damage was from being moist from the leaky heater core. I found replacement floor pan sheetmetal from 50resto and dallasmustang. I also know an experience welder that can take care of them.
What is the recommend method of installing them? Should I remove the old floor pans or install the replacements over the top? I was looking around online and I have seen it done both ways. My thought was to leave the old floor pans in place and go over the top. That way there is another layer and should be a little stronger. Before I did that though, I wanted to see what other Fox mustang owners recommend.
