Does anyone know the specifics on the hardware required for the 42-47 1/2 ton pickup running boards? I've looked everywhere and I can find just about everything but hardware for this specific years' running board. I would think the running board to fender hardware is not that critical, but I would like to use the proper hardware to connect the running boards to the frame mounted brackets. Thanks in advance.
 
Not a 40's pickup running board expert, but in the mid 30's the pickup running boards were attached with carriage head bolts, a split lock washer and a nut.
All items that should be available.
Now, if by the 1940's, your frame does not have the square head holes for the running board attachment, then my information will not apply.
 
Morning,
I have been researching/looking for the 6 each side carriage type bolts for attachment of the boards to brackets under them. I have info we could share if these are the attachments you are talking about.

I think you are correct about the carriage bolts. I will just need to remove an installed bolt and see what it is and go from there. The boards themselves attach directly to 3 brackets. These brackets attach to the frame, but the board only attaches to the brackets. Was just hoping to find something definitive. I've got the green book and that is not helping as far as the hardware goes. Thanks!
 
2 of the 12 i need for my Period Correct running boards installation can be used again. I need 10 more. No one sells them, i have a quote from a machine shop to make some, very expensive but i will probably bite the bullet as they are very visible for a Period Correct restoration. they have a special head, a square under the head.....I would be interested in what the Green books says if you will pass it on. Thanks.
 
The bolts are carriage head with an integral spacer under the head. The spacer part is what clamps the board to the bracket...not the carriage head. Using a regular carriage bolt will crush the board in the area where the bolt goes through. It's important to use the proper bolts. I've never found anyone that has them available.

Got pictures? I used regular 5/16-18 carriage bolts for my running boards and don’t have a problem.
 
Bob Drake has bolts listed for 1937 - 40 car and truck part # 78-16453 Midwest early ford has the same part # listed for 1937 to 48 cars. I know that the Bob Drake bolts are correct for a 1939 ford pickup. I agree they are a plow style bolt, I think they are 5/16 fine thread by 3/4" in length.

Here's the table in the green book. Not specific to 42-47 Comm.

47 Tonner Period Correct bolts are 1 3/8" long, i am not sure 78-16453 are the right bolts, i called Drake & Midwest a couple of months ago, neither could tell me they stocked the bolts i was looking for.....
 
I probably have some factory bolts somewhere that I removed...looked, but didn't find them.
These running boards have a 1/4" deep box welded to the underside of the board. That box is what sits on the mounting bracket. The integral spacer on the factory bolt clamps down to the inside bottom of the box to the bracket, so the board top won't be crushed. You can fill the space in the box with a flat piece of nylon material, then use whatever bolt you want to attach the board without crushing the top. Nylon material works well because it's flexible enough to get past the outer curvature of the board edge and inserted fully into the box. Drill through the nylon and install your mounting bolts. With the box filled there is no crushing the top of the board. Good luck!
