71-72 chevy buckey seat imstall.

[71gmcC15]

i got my bucket seats form randy 500 today and stared to install them. I assembled the mounts and oiled up the driver sliders and bolted them to the seats I got the passenger side holes all drilled. I'm still working on the driver side. Did some seaching on here and found that the driver side need to be over an 1 1/4 from the bench mounts. I had to dimples there so that made drilling easy.Need to get more 5/16 x18 bolts to finish the job.

might want to touch base with Roger Koop and take a look at his thread regarding the under cab brackets. http://67-72chevytrucks.com/vboard/s...d.php?t=557195

Yep I see that he makes them might order some or make my own. Will not look as nice as his but should do the job. I was honestly think of just using a thick washer. Not shure if that is a no no or not. The factory's brace is not that thick and the seat belt in not attached to the seat so I dont really see the harm. But please correct me if I'm wrong.

If a washer was enough GM would have used a washer. It is a safety consideration. Seat mountings must meet certain test requirements set by NHTSA. I design seat mountings for RV's and oversee the destructive testing. I encourage you to install your seats to at least factory specifications.

Nice addition to your interior. A nice console and some new carpet and its going to look great.

The thing about using a large thick washer is for a lot of incidences they will be fine. But its not about you, its about your passenger and the public at large. When I was very young with my first car,it was something we drug home (57 Chevy) and cobbled together.

On one of the first runs me and a buddy took it for a run when my dad wasn't home,which was against the rules. Tossed the bench seat in, stomped the gas, and the seat flipped over on us. Luckily we were ok, didn't hit any thing or any body.

Seat belts? We don't need no stinkin seat belts. Same car, driving too fast, we went flying around a corner and hit a patch of gravel. We spun out, went through a fence, some trees, and smacked into a concrete wall. Totaled the car, and it knocked us around pretty good. We were lucky, and I felt horrible my best buddy could have been hurt much worse.

Ive been pretty careful since then. So install those buckets correctly, just in case.

Hi 71gmcC15, here's a link to a thread showing installation details that should help you out.

Ok seems like every one says dont use big washers get the factory braces. I here. I did finish installing them with big washers. I will how ever some time in the near future replace them with the correct brace. They are pretty solid and dont think they will rip out of the floor in an accident.

I’ve installed several sets of factory buckets in these trucks and used large washers as well. If the seatbelts were integrated into the seats I would not use washers and I would certainly use something stronger than the factory bucket brace.

That's my thought exactly.

If all they needed were big washers GM would have used big washers. They are not in the business of spending money they don't need to. Things were pretty basic back in those days and safety was not top priority on the list like it is today yet they went the extra mile on the bucket seat trucks. Why do you think that was? Witness a seat failure some time and you'll think twice. Don't let anybody you know or love ride in the passenger side seat.

No doubt a factory style install is a better way to go and I went that route with my K20. However, the GM K5 passenger bucket seats are hinged to flip forward with the rear portion barely affixed to the floor at a single, non-permanent point of attachment that is probably less secure than the aforementioned washer arrangement.

Some (not all) K5 rear seats used the seat brackets exclusively as points of attachment for the seat belts and an install using washers in this setting would be dangerous.

If it helps my old seat just had two bolts up front with a peace of wood spacing the back. Not bolted down at all. Drove it like that for a year. If safety is your concern then I wouldn't drive these old pickups. I still have the gas tank in the cab to.I am going to make some better braces. As for now it will be fine.

Best reason ever for going the extra mile securing the seat(s).

I am going to brace them more . And he should of shut that thing down as soon as he left the line. Thing was all over the place.

The seat belt and your body in that installation hold the seat down. You are hammering your head into something with 2 point belts. Rearward that seat mounting gets compromised and you and the seat exit the truck. So many try to justify hacking things together with no regard for human life. Go ahead guys and risk yours but as I said before leave the passenger seat empty.

The response was directed to Deadhead. Do what you want. You are making an informed choice now.
