Re: Longbed mounting hole placement

I put my boards in today. I definitely dont think you want my measurements, My boards seem too narrow, so the gaps between them are too wide.

Suggest you check out

Make sure your boards are correct overall width...there are many different widths depending on what bedside or box you have.

I usually end up with about 1/2" - 5/8" between the boards where they sit on the cross rails...

What dimension did you cut your boards at ? There is supposed to be a good amount of play for movement as the wood grows and contracts

Re: Longbed mounting hole placement

7 7/16 wide for the widest ones. I think part of my problem is that I mounted the second board (the one that is cut out around the wheel well) too close to the bedside, so there is a large gap to the 3rd board. I can probably take the bolts out and move the board inward a little bit to tighten things up.

Re: Longbed mounting hole placement

I am attaching a pic of the bed board mounting showing how the wear strips are embedded into the bed wood...thanks to GMCpauls for the image...

There needs to be approx 1/2" - 5/8" inch gap between the two boards where the bolt goes thru, to allow for expansion of the wood due to moisture and weather etc.

The bolt should be 1/4"...so you should have approx 1/8" to 3/16" either side of the bolt shaft.

I always find it easier to not bolt down the 3rd board in from outer edge to the wheel covers until all of the bed planks are in place.
