The elevator bolts I got are dead flat on top of the head and tapered under it. The originals are more like an extra large and low head carriage bolt that is flat on the under side and domed on the top.

Perfect timing.

If you use elevator bolts, you will need to grind about 1/8" off of one side of the head make it fit into the opening in the running board. The head of a 1/4-20 elevator bolt is 31/32" dia. The head of a 1/4-20 step bolt is 13/16" dia.
The previous owner of my truck used elevator bolts with one side of the head ground down and they worked fine. I have the boards off to prep for painting and will replace with step bolts from the Filling Station. However, elevator bolts might be a better choice because they are available in stainless.
