I purchased patch panels for in front of the seat base last summer from Chevy Duty. I do not know if all vendors sell the panels from the same manufacture, but Chevy Duty sells TriPlus and Auto Concept parts (I may not have the names exact, I am going off of memory). Anyway, here is a picture frm July 2003 aftet I installed the panels. Its not a direct shot of the panels, but its the only picture I have that shows them.

These panels extend slightly past the front of the seat base (about 1"). They seem to fit decently, but took a little work to get them in.
