Another tip, when you cut your seat tray out, put the new pan in place, trace around it. Gives you a guide as where to cut. Then, techniques run amock. I cut about 1/2" inside the trace line. Then, I punches holes every 1 1/2" to 2 inches for spot welds. Then, on the seams, go and run spots every 1/4 inch till it's all sealed. Then get some gray 3M Seam Sealer and run along all the floor seams to prevent rust. It's not as hard as it looks. Did mine in a lazy weekend. Again, this is just how I did it, I'm sure others will know more on it, as it's my first time. Ohhhh Billly...
