That left me with a hole in this crazy spot on the rounded end of the hump that the seat mounts to. I didn't have a patch for this, so I used the part I'd cut out as a pattern and made my own patch. Too many curves for me to make it out of one piece, so I started with this piece that I could get the bends/curves I needed. It had to have a pretty big relief cut/hole but I'm pretty happy with how it turned out. Don't mind the ugly burn holes. After all the sheet metal welding practice I've had by now, I think that the only skill I'm improving is filling the burn holes I make
