Rear quarter rust repair panel help please

I need to fix the quarters around the wheel wells on the Scamp. We bought patch panels from the Paddock that by the description and measurments seemed to be enough but they aren't. It's only about 3/4 of the wheel well opening omitting the front 1/4 down to the rocker area. In the rear it doesn't extend to the valance at the bottom either, it's cut back for some reason.

Needless to say the web site doesn't have a pic of this and doesn't really describe it well either so these are pretty useless to me now that I see them.

I need the entire wheel opening that extends all the way back and at least 4 to 6 inches in front of the opening.Does anyone know where I can find what I need without buying an entire quarter panel?
