Re: Steel Bed Floor?

If you use the 67-72 steel floor in a 64-66 fleetside, do you use the 67-72 wheel tubs or 64-66?

The 60-66 tubs are the only tubs that fit your bedsides.
The 67-72 and the 60-66 floor pattern is the same.

These would have a somewhat smooth surface but still resemble the wood floor. I don't know how cost effective it would be either......just an idea.
Coworker took his wood bed apart and did just that with diamond plate. Looks pretty nice, though I don't have a picture of it.

Before installation I coated the wood on all sides with fiberglass resin (no cloth just resin) to completely seal the wood. I then rested 48" wide diamond plate on top and bolted it in place. I didn't have any way to get it under the angle rails, so it's centered and just touching the edges of the rails.

For 10 years I had a Gaylord bed cover installed so nobody could see it anyway. It's certainly not show worthy, but for a working truck it's easy and looks nice. The only pictures I have are very poor quality but show how it looks.




I've crawled under and looked at it and other than having 10 years of road dirt on it, the wood looks good as new with no deterioration.

Somebody did Steel Diamond Plate in mine.

Re: Steel Bed Floor?

Hmmm... Diamond plate in the back of my '62 long-step 4x4 would be pretty easy, and probably a lot cheaper than a wood bed kit...

Lightbulb Re: Steel Bed Floor?

Hello guys I finally got around to doing my metal bed swap, so here is how it went started saturday morning and finished with the install sunday evening. it was pretty straight forward, I removed the old wood and slats then the sides tailgate and front header. after all that was done I started by putting the metal bed on the truck and then bolted the side and header on. once that was done i had to cut the front header 3/4" and rewelded it back to gether so it could be bolted to the bed.

Re: Steel Bed Floor?

I just bought my '69 Long-Horn (8.5 foot bed!)from the original owner's son last year. They were both metal workers and replaced the wood floor about 15 years ago. They used steel diamond plate. I forgot what thickness, but I remember thinking "dang that's thick". The sub-flooring is all square tubing welded to the frame. So needless to say I won't be pulling the bed off this thing for some time!

Re: Steel Bed Floor?

I used 3/4" spacers to make up for the space difference.

Re: Steel Bed Floor?

I put a 72 metal floor in my truck bed. I know that these trucks used the same parts up to a certain year in the 80's. I wanted a bed floor as close to my year as possible, because in my mind I hoped it would be less work.

Re: Steel Bed Floor?

I've been using 67-72 steel bed floors on 60-66 trucks for many years. 63-66 is a drop on and bolt up situation since the frames are identical to 2nd gen C10s.
I'll likely never use wood for a bedfloor again.
Especially since steel floors are a fraction of the price of wood.

Since there are no formed sections on the floor sides where the gas filler/s would be located on the bedsides, that steel floor would most likely be 67-72.

Re: Steel Bed Floor?

For anyone who was like me and wondered about the 73-87 bed floor, it does work. I just completed the swap on my 64 GMC with an 86 GMC bed floor and it was quite simple to do. I will share photos soon of my swap.
