Seat mounting nuts
« on: August 18, 2006, 10:02:00 pm »
I just put a pair of leather power buckets from a late 90s S-blazer in my 85 Chevy to replace the velour bench. I drilled new holes but used the rear outer factory holes as my locating points, thus having to drill 3 new holes per bucket seat. I used a grade 8 3/8" bolt with grade 8 nuts and grade 5 washers and lock washers to secure the bolts but I would like factory style mounting nut/block. The factory uses a steel cube with a tapped hole in it to accept and hold the seat bolt, and it's welded to the floor pan. I would like something similar. Anybody know where to get these? The other way I was thinking was to get double up on fender washers and weld those to the floor pan, and then weld a nut to the fender washers. Crawling under the truck everytime to take the seats out really sucks. That and the outside front bolt on the passenger side is right above the pass. side gas tank (I don't have a drivers side tank), and for now, there is no bolt in there.

If anybody is interested, I'll post the series of pics I took while doing the installation of the drivers side.

Yes please post pix. I have a Saturn that was donated to me with zero miles on it and the seats are brand new never even sat in so they are getting a transplant into my truck. I am going to fabricate something nice and will also take pix.

If you put the pics and text in a word document I will post it in the tech section.

Can do. I've uploaded the pics to my cardomain web page. Does that help at all? I was thinking of replying to this thread with a link to each pic and a short write-up of what I did.

I figured out what to do about the bolt on top of the pass side saddle tank. I made a steel strap that goes from the bench seat bolt hole over to where the bucket seat bolt hole is and both are bolted. Not perfect but whattya do eh?

What I'd like to see is the underside of a Jimmy floor pan or a truck that had bucket seats to see how and where they put the bolt holes. I'm still searching for those seat bolt mounts that weld to the floor pan. Haven't found anybody selling them yet.

You should be able to find weld lugs at the hardware store, or maybe even your local welding supplier.

You could go to a metal mart and have them cut you 1/2" pcs. of 1x1" square bar,drill and tap the center.This will give you some nice lugs.

Can you get to the under side? Plug weld a square of sheet metal the same or a bit thicker gauge than the floor tin where your nut needs to be, drill a 1/2" to 3/4" hole. Weld the correct size nut to a fender washer and then weld the fender washer over the hole with the nut down throught the hole, and you could weld the nut from the bottom side too.

Some people are like Slinkies. Not really good for anything, but they still bring a smile to your face when you push them down a flight of stairs

Instead of replying to, start a new thread under body forum and add your info and I will move it to the tech forum when you are done.  I was going to make a page on the main forum for it though.

Will do, Chris.

As for the mounting nut, my original plan was to have a couple of #5 fender washers welded to the floor pan, then a #8 nut welded to the washers.  I'd like a more factory appearance though and the factory mounting nuts are nice for this.

This is the underside of my truck right now. Here you can see the factory mount. It's a solid steel square with a hole tapped in the center. That's what I'd like. I could go to a metal mart and have it all done, for a lot more than buying them already done I'm sure. Next to it is my new #8 bolt and nut with #5 washer and lock washer. Nothing is welded and it's a pain to try and get really tight since the washer and nut will start to slip once you really start to torque on it.
