71-72 chevy buckey seat imstall.
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.

Re: 71-72 chevy buckey seat imstall.
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.

Re: 71-72 chevy buckey seat imstall.
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.

Re: 71-72 chevy buckey seat imstall.
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.

Re: 71-72 chevy buckey seat imstall.
That's my thought exactly.

Re: 71-72 chevy buckey seat imstall.
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.

Re: 71-72 chevy buckey seat imstall.
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.

Re: 71-72 chevy buckey seat imstall.
Best reason ever for going the extra mile securing the seat(s).

Re: 71-72 chevy buckey seat imstall.
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.
