73-87 seat belt tech - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Pyrotechnic · 09-09-2009, 12:45 PM

I haven't seen any info on seat belts on this site so I'd like to start a thread to see if we can collect our knowledge. Until I started trying to replace my seat belts, I thought all seat belts for these trucks were the same over their 14 year run. Not true.

73-74 had lap belts. Some may have had 3 point belts as a dealer option but most I've seen just have lap belts.

75-77 had 3 point belts which utilize the retractor on the floor from the lap belt, and adds a retractor behind the seat.

78+ did away with the retractor behind the seat. The belts still use dual retractors, but both retractors are now integrated into one box on the floor.

I tried putting 78+ belts in my 77 and it did not work. Seemed like they moved the mounting hole on the floor for the later trucks.

Hopefully this helps and if there is anything I missed feel free to add it. I would also be interested in seeing what you did to restore/replace your seat belts if you've done it.

Ahh...poop. I was just going to gut a 'burb for it's doors and belts.

What about the buckles on the seat? Are they interchangeable between the years/bodies?

LMC has these http://www.lmctruck.com/icatalog/cc/full.aspx?Page=110 and http://www.lmctruck.com/icatalog/cc/full.aspx?Page=111

Pyrotechnic · 09-09-2009, 10:31 PM

I tried some of those universals from LMC. Didn't like the way they fit at all so I sent them back. Also, the single retractor arrangement made the belt feel a little weird to put on. That retractor had a hard time taking up the slack when you took off the belt as well. You had to feed the belt back in before you got out.

S10 fan I would like to see the way you installed those if you have any pics.

My '77 had the two seperate retractors originally, but I found that they would continue to "cinch up" every time I moved in the seat or hit a bump, so that eventually they would be extremely tight on me. I ended up using belts from a newer model, and as Pyrotechnic says, the mounting points are different. I just drilled a hole in the correct spot and mounted the new ones with a bolt and nut. Also, the male and female buckles aren't the same between the newer and older styles of belts. I had to replace the short female belts too, but naturally they used the same mounting holes as the originals.

My dad has a '76 with lap belts only. I think it was a fleet truck at one time.

ShowSS12 · 09-10-2009, 10:49 AM

I just had my stock belts rewebbed...... But I have an 87 which used the dual set-up mounted on the floor next to the seats.

2tone77 · 09-10-2009, 05:49 PM

How do you get your belts rewebed? Thats what I would like to do, as my belts work fine, they just look bad.

ShowSS12 · 09-10-2009, 06:04 PM

I just took them down to my upholster and he had some grey seat belt material which he stitched to match the factory stitching so the look OEM all I need to do now is paint the beige cover grey and install them... I'll see if I can get a pic...

i know on my 77 the farther you drive the tighter the seat belts get makes it hard to breath

Tony_SS · 09-12-2009, 06:27 PM

Here are the ones I'm using.. the don't fit exactly like stock, they just require a nut as a spacer but you cant beat the price!

tony and s10fans are EXACTLY the same as a stock rear belt out of 87-94 s10 blazers

Same here. Bump, click, bump, click. gasp.

S10Fan · 09-13-2009, 10:11 PM

OK, here ya go. I mounted mine by making brackets from sections of 2" square 3/16th wall tubing. The brackets were mounted in the stock locations using the stock bolts and holes.

1969stepside · 09-13-2009, 10:12 PM

can a set of 73-87 belts work in a 72?

Pyrotechnic · 09-14-2009, 11:31 AM

Nice job S10fan. Looks like the universal belts work pretty well with those brackets you made.

Since my 77 has those mounting points behind the seat, I'm thinking about running these style of belts but putting the new retractor behind the seat and the lap belt anchor on the floor. I'm trying to avoid rewebbing/rebuilding as I've heard it's costly so that leaves universals or finding something out of a newer vehicle, maybe those S10 belts that TheSunDanceKid mentioned earlier.
