Bob,
I got my panels from K&K. They are well insulated and fit well except that the left panel was made for an automatic transmission car and didn't clear the clutch pedal, so I had to cut a corner out. They come only in black. I assume they could be painted with a vinly paint to be the proper color for the car, but I haven't tried this with mine yet.
My left panel simply has an area cut out for the pedals. I saw a photo once that made me think the left panel originally had a hole for each pedal, with a slot for installation, but I don't really know.
