Early Body Bracket to frame bracket

Maybe this has been discussed before, forgive me if it has. So I'm in need of 6 body brackets for a 1912. These are the brackets that mount to the body that in turn mount to the frame brackets to bolt the body to the frame. Langs sells the brackets but the holes are round and not square. What have you done to mate the bracket to the body? Have you modified the bracket to a square hole to accept the carriage bolt or just used what was there? Does anyone have an original set?

Here is the brackets in question
Thanks for the help.
Mike

The "square" hole brackets were for the back 2 on the Runabout as the rear fender irons attach at that point - the carriage bolt enter the sill then the iron is mounted - can be a tough one to find !

"the carriage bolt entered from the INSIDE of the sill, I meant to say.

So if I'm hearing you correctly the ones with the square holes were for the rear brackets only right?
Thanks

I believe so - I have the same set on the rear of my wife's '14 - '15 Fire Chief's rig (Runabout chassis) - with the front & center brackets w/round holes.

Larry Original Smith might chime in here as he has an early brass Runabout also.

As a rule of thumb, usually the square under the head of a carriage bolt usually goes into the timber, the square being there to keep the bolt from turning. So that means the nuts are usually at the end of the steel component, that part acting as a washer. This is the way those brackets are usually fastened. If there is metal on both sides of the fixing, as mentioned, then one of the components needs to have square holes to keep the bolt from turning. Punching holes in the bracket would be easier than forming square holes in the forged fender bracket. An easier fix would be to use a hex head bolt, but that may mean extra time for the assemblers.
This same scenario occurs with the metal hood shelves on black radiator cars.

The round hole brackets are correct for a 1912. The early bodies have an exposed stringer at the bottom of the body, that mounts sideways to the brackets in question. The carriage (or step) bolts mount from the outside of the stringer, thru the stringer, with the square shank under the head, buried into the wood. The round shank and threaded end pass thru the stringer and thru the round holes of the bracket, with a nut (3) holding the bracket in place to the inside of the stringer.
