The fuel fill cut out took more quite a bit more figuring to make the pattern. I started out making a pattern of the metal cover's footprint by cutting a notch in the pattern board and holding it in place against the inner fender well. Then tracing the half circle with a Sharpie.
I then measured the width of the bolt flange on the fuel fill cover. It was 1" 7/16" wide. I laid out this measurement on each sided of the pattern (Silver writing). I measured the distance between the two marks and divided that number by 2 to get the radius of the inside of the fuel fill cover.
As there was only a small bit of the fuel fill cut out left in the old wood I took a compass and put the point on one end of the remaining wood and made an arc. I did the same on the other end. (Photo #2) The point the two arcs met was my center point for the radius of the cut out. Once the arc was drawn I connected the ends to the edge with a tri-square.
Once the two cutouts were laid out I did some measuring to compare my layout to the inside of the truck. Everything seemed to jive so I made the cuts. And after a bit of sanding to clean things up I slid the new piece into the cab and with a couple of taps it was in place. (Photo #3 & 4)
