Seat-Belt Upgrade on 1975 C-10
« on: June 29, 2020, 07:40:22 PM »
Hey everyone! I have a 75 C10 Cheyenne with lap belts. I recently picked up some 3 point belts from an 85 hoping they would work. Does anyone know if this is possible? Thanks!

Yes but don't call it an upgrade. It's a retrofit. Upgrade is subjective  :P

Retrofit first it is then. Any advice on how to do it? The driver side mechanism has a wire connector that, according to the 85 wiring diagram, connects to the convenience center but Im not sure if I need this to be connected to power in order for the mechanism to work. Or if its simply plug and play? Im super new to this, sorry!   :o

It does not need to be connected to operate. Seat belt reminder lamp is all you will lose out on  ;D

Update. The 85 seatbelt mechanism housing is too big for the space between the seat and the door. If its installed then the door doesnt close properly. Time to find other seatbelts!

Keep in mind that the upper support needs to be bolted (secured) the a strong support or the three point belt is useless. I had cut out the rear window metal and welded in new metal. It did give me an opportunity to see the insides. There is a metal support that the seat belt is bolted to. Getting the upper belt point bolted into the support you give you a solid connection. My pisture will show you the internal support brace.

That makes sense, I wish I had welding skills haha. There is a mounting hole already drilled in my truck on both sides from the factory so Im guessing they reinforced the connection to make it solid. My issue is down below where the retractor mechanism bolts to the floor.

What year cab? The provision should be right there already.

Appears his is a 75. Did it just have lap belts?

However, it appears there must have had the three point option if there is a bolt hole for the upper point. If there was a three point option and you only have a lap belt, do a Web search and see if you can find one from a salvage yard.
