I just reopened an email John Gambil had sent me a few months ago when I was trying to get the 70D seals fitting better. He had a notation about parts that are in the works and they include:
dimmer switch covers...powder coated
upper and lower heater delete plates
door panel bottom retainer strips...stainless steel.
Hopefully John will chime in here and let us know what's going on with them. If they're the same quality as the 70D window support strips he's had made, they're going to be a great addition to available parts lists.
