OR Wood floor replacment bolts and metal strips. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**HO455** · 11-29-2021, 05:58 PM

AWhen I replaced the wood floor in my Suburban I found that the 5 smooth top countersunk bolts (1/4-20 Plow Head bolts) that are across the rear of floor are not available.
These fasteners are usually rusted and have a tendency to twist in two when removing. I ended up modifying the closest bolts I could locate on my lathe to make replacement bolts. (Quick word of thanks to Richard 2717) These are a close but not perfect replica of the originals. The biggest difference being the countersunk area on the back of the bolt is smaller. The downside of this may be a reduction in how much torque the bolt will take before the head would deform. I had no problems with this when I installed them in my floor. The bolts have been sprayed with cold galvanizing paint. I have 10 sets.

I also have 2 of the metal strips that go across the rear that I had made. Mine was too rusted to reuse. These pieces are not drilled and countersunk at l present but I will do that before shipping. The reason I haven't done it yet is that when I did mine I noticed the holes were not consistent in their spacing. I would need to know the specific spacing measurements from your Suburban or that you would be okay with having to drill additional holes in your truck to get the bolts installed.

Here is a link to the floor replacement part of my repair thread. It goes on for several pages with a couple of detours before completion.

https://67-72chevytrucks.com/vboard/...698377&page=20

Pricing for the bolts is $25.00 for a set of 5 shipped. (As of 10/23)
Pricing for a rear strip is $45 plus the shipping.
I also have one factory front hold down strip with extra holes drilled in it for $25 plus shipping.

There are no more of the #1 bolts (See post #9) available at present. (12/23)

More information on the bolts.

Photos of the finished strip I used in my Burban.

**richard2717** · 11-30-2021, 02:35 PM

Those turned out nice

**HO455** · 11-30-2021, 11:55 PM

Thank you Richard, for everything.

**HO455** · 01-19-2022, 05:53 PM

Additional photos of the countsink or dimple process. 1st one is the die I made to do the job. 2nd one is test fitting in the factory piece. 3rd is the testing program.

**Getter-Done** · 01-22-2022, 08:48 PM

I like your punch and die setup

**HO455** · 01-25-2022, 07:18 PM

Thank you. It was an enjoyable little lathe project.

**HO455** · 04-10-2022, 11:01 AM

Bump to the top.

**HO455** · 08-08-2022, 02:32 PM

I now have 4 sets of 12 of the # 1 bolt in the first photo below. They are not an exact match to the ones the factory used (Photo 3). The factory ones had 7/8" head with a 1" long 3/8 shaft.

These have a 1" head with a 1- 1/2" 5/16" shaft. (Photo 2). They do however have the same shallow dome head as the factory bolts did. Visually They would be amost indistinguishable from a factory bolt once installed.

Modern carriage head bolts have a much smaller head with a rounder dome head or the other option would be a head with a slot and no square shank under the head. Photos 4 & 5.

I will include 12 of these for no charge with an order of the rear bolt set.

**knuckle-nurse** · 08-14-2022, 12:22 PM

I will take a set. Thanks.

Hi, I'll take one set of each of the two types of bolts, thanks. Will PM you.

Payment arrived. PM sent.

**HO455** · 10-26-2023, 03:25 PM

Bolts shipped.

Just an update to the original ad I posted. Due to the increased cost of shipping a bolt set is now $25 dollars.

And I only have one set of the additional free bolts left. Order soon!

Hi I would like to purchase a bolt set.
