Yes I do, you get it from Rubbermaid. As in thier trash can. The chin scoop is Exactrep and the belly pan is Trash Can. I hit one with my trailer and realized it, here's my pan!
Indesrtuctable, flexible, paintable and CHEAP! Took about an hour to lay-out on cardboard. There was room in the circumference of the trash can for two pans.
Just an idea if you don't find anything else.
Im looking for both. im going to wait on working out the layout of the belly pan till my slip ons get here. Did you make the chin scoop yourself aswell?
