I have looked but cannot find the female end of the driver's seat belt for my "93 GMC Coach House. I would like to get a tan one but will accept about anything at this point. Do you know of salvage yards that might have something along this line?
I needed a seat belt one time and was told by a couple of salvage yards it was illegal to sell used ones. That may just be in Oklahoma though. I guess that really didn't answer your question though, sorry.
I searched and searched for seat belts on a project years ago. I finally found what I was looking for sold by some mail order company in Chicago. When I got them in, I was flabergasted to find out they were fabricated a mile from my office in Oklahoma City. Try this link to the same manufacturer. They are OEM for lots of specialty vehicles and might tell you where to go if they don't have what will work.
