As you can see in the pics, I welded a couple bits of metal together to get the shape spot on. Also had to do a bit of bending. Did it all with a TIG welder, small grinder, mutli grips and hammer.
Not sure if I mentioned it on my site, but if you do a repair like I did at the base of teh rear wheel arch, you need to be sure to include a hole for water drainage or it will rust again.
