How were the original running boards secured to the brackets and fenders? I would imagine by wood screws inserted from the bottom up into the wooden running board. If that is correct, what type of head was on the screws? Possibly, Round head? Lag? Or was it possibly secured by carriage bolts countersunk (and covered by linoleum) from the top with square nuts on the under side?
Is the replacement linoleum self adhesive or is it glued in place?
Any help would be appreciated,
Gary

The original linoleum on Dads car were not glued. They just layed flat and were held down by the zinc trim around the edges. Not sure about the hold down bolts but can post a picture of his driver side running board with the linoleum off. Not sure how helpful the pic will be since I didn't clean off the stuff sitting on it when I took the picture.

Bob - you're right, it's kinda hard to tell what I'm looking at in the photo. Next time you're around your dad's car, can you check how the boards are attached to the brackets and the type of bolts? Are your running boards not original?
My running boards are 3/4" solid oak in good condition, so I probably won't be replacing them. But I would like to attach them like the factory before I replace the ribbed rubber mat with linoleum.

The fasteners called elevator bolts.
Do a google search and you can see a picture.

The running boards are held by bolts that are replaced by elevator bolts. Those are large headed carriage bolts. The head profile is not exactly the same for the modern bolts but as close as you can come without making them special. My linoleum was nailed at the outer edge and the nail heads covered by the zinc molding. Did not find any adhesive on running boards or floor boards. I cheated and replaced the zinc with galvanized steel bent to the same profile as the zinc was a little rough.

So, the elevator bolts are beneath the linoleum that is held in place by the edge trim, correct?
Thanks,
Gary

Plowshare bolts are flat headed and have a stamped in grabber under the taper to keep from spinning...May be the same as Elevator bolts though.
