Somewhere along the way I had cutout the inner portion of the rear fenderwell to gain access to weld and do some other things. Since I was going to need to modify it anyway for the new suspension travel then it was better to cut it out and fab a new piece to replace it.
So I took some posterboard and traced the outline of the cutout portion onto it so I could transfer it to a new piece of steel sheet. I then figured out how big the notch needed to be cut into the new sheet to clear the suspension travel. After this was trimmed to fit then I was able to form a bead along the lower lip to match the existing bead on the panel.
