I'm glad to finally see that there is a gmt800 specific forum now. I have a project that I have been working on that I need some info on. I purchased a 01 2500hd crew cab short bed truck to "restore". I have dealt with lifted trucks for many years and over the course of the last 10 yrs primarily diesels. I decided this time that I was going to pick a worthy "project" and build it to suit myself out of my wallet. I picked up a Southern rust free never been wrecked 6.0 truck to work with. I have already completed a sas with a dana 60 in front, and I have rebuilt both axles front and rear with 4.88 gears. I plan to pick up small things that I need as I go which brings me to my question. My door panels are the worst for wear and need replaced. They have a few small tears in the vinyl. Will the panels from a 03-07 classic truck fit my doors? I know the switches are different but I imagine they could be wired in. I believe the panels will bolt right in just like they came from the truck. I called one large scale junk yard and the kid on the phone said they wouldn't work, but I am satisfied he was telling me what his computer in front of him said. Has anybody put the 03-07 door panels on the 99-01 trucks?
