I can’t seem to get the search function to work. So can anyone help me out. Im looking for the teflon/plastic guide/slide. For the sliding door. My door drops horribly. I saw a link posted long ago. For parts to rebuild but cant find it anywhere. I found the link for roller. But not the guide.
Most people just ditch the bottom fixings as they tend to crack the bottom lip on the doghouse anyway and it works fine without them. You will need to sort the top latches though. My van is 1979 but I presume the same applies to a 76.
If your seats use a threaded stud through the floor, I would highly suggest trying to use that to mount the base plates of the chair bases. You can also make adapters out of sheet metal for either the seat to the base and/or seat base to the floor. Reason I suggest that is the unibody frame rails get int the way underneath so drilling new holes may not be easy unless you’re using lag screws, which I personally wouldn’t trust the strength of heaven forbid there’s an accident.
If the van has the original hood, it should say what transmission it has, my guess is a standard 727
It's most likely a misplaced ground wire. The door switches provide a ground (-) for the factory interior lights. Sounds like someone mistook that door switch wiring for a good spot to tap the vent fan and cabin lights onto. You'll need to trace and find a better, solid ground connection. Sounds like, from what you say, that the "hot" or power side is okay.
