Right so I didn't like the proximity of the license plate holder/light assy to the rear wheel and at one point I think the wheel touched the plate which is just not good. I'm gonna use the existing seatpan as a plug for a mold to create a new one.
Here's how the plug looks right now, a bit higher and stretching back a bit more. I actually find the more horizontal line to work a bit better; we'll see how the final part comes out. next up is to prep this piece for constructing a splash mold, so fine grit sand paper, wax, wax, wax, pva, boogie nights!
I don't have the best before/after pics so the after pic is a bit distorted via paralax, but hopefully this illustrates it well enough
