Seatbelts? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Oregoon · 01-14-2015, 05:05 PM

Hello, all!

My '74 GMC Standard Cab is my daily driver, and it features lap-belts.

While I dig the clean look of an uncluttered cab, I like being alive and feel that some shoulder belts would be in my best interest.

From what I can see, it looks like a case of finding the appropriate color (in my case, Golden Brown/Saddle) from a donor truck, and bolting them in.

Am I correct, or is there something I need to know? Are shoulder-belts the same in all years of squares? Any other years/models that will work?

Thanks in advance.

I have a 74 cab and it h ad shoulder belts standard I f you add them and there is no bolt hole you should probably weld in a section of a inner b panel to make it real safe

There are existing threaded bolt-holes on the door-pillars with a plastic cap over them.

From what I can learn by searching around here, shoulder-belts were a dealer-option in '74.

Just wondering mainly how interchangable the later factory shoulder-belts are?

Or, is there a reasonable aftermarket source anyone has used?.

My interior is just about perfect, and I'd like to keep it as close to stock as possible

Confirmed again my 76 has the threaded hole in the pillar as well.
My Dad had some later model should belts in it for quite a while. (before I probably not so smartly removed them for some chrome latch lap belts)

Around 360k miles mine had worn to shreds. I found some good ones on Ebay. If you can find some in a similar truck, then you can look at the offerings on Ebay that look exactly the same. I think I remember the ones from 1981 on were a little different. Rather than find out if they would work I found some that were exactly the same.

What year did shoulder belts become universal?

I could be all wet on this... but if I remember correctly, federal law required them in cars by the '69 model year and light duty trucks by '77.
