Thia my first thread, a little about me, I've never not owned a truck, I have 4 at the moment, just enjoy working on the the old ones. I just got a 1987 GMC Suburban 1/2 ton 2wd, it's a little rough but is a good vehicle. There is a hole in the driver's door panel next to the window switches and the door lock switch, looks like a factory hole. Anybody got any ideas? Thanks for any information and will be look forward to hear from you!
