Floor Pan Replacement
I was getting ready to paint the rear floor and found some pin holes,I was going to make a patch and found more holes so replacement was in order. I take you along as I replace the floors on my fairlane.
I ordered a replacement floorpan from e-bay. My plan was to keep as much of my floor as possible. Here is a pic of the tools I used to do the job.
The first step was to measure the floor pan and cut off what was not needed. I cut the pan with the cutoff wheel.
I then drilled out the spot welds on rocker and drilled holes on the pan were it meets rocker for some plug welds. Now lay the new pan overtop of old pan and put a few screws in it to hold it in place.
Using a combo of air saw and cut off wheel with very thin blade cut though both the new pan and old floor tack welding as we go every 3 inches or so.
Here is a pic of the pan installed with tack welds and plug welded at rocker.The pan is butt welded a perfect fit.
After tack welding all the way around move back and fourth to keep heat down.I used .23 wire on this job and keep the heat setting on the lowest setting.
Here is a pic with the floor pan installed from the bottom.
After all welds are ground down I like to use brush on seam sealer and rub into seam both top and bottom.
Well there you have it,I spent about 5hrs with this repair with a little sanding and paint the seam will disappear...ED
Take your time. It's a very straight forward process. Just be sure to use small tack welds one at a time to prevent warping to panel from heat.
