anyone have the sizes and type of nut and bolt used with the mounting bracket attachment to the running board in early brass cars?
R.V. Anderson probably has them.
A '14 uses a 1/4 in. carrage bolt.
I don't know what was used at the factory, I just used 1/4" bolts and square nuts. Probably non-stock.
One other non-stock thing I did was put rubber grommets between the bracket and the nicely painted runningboard. The runningboard is so irregular that there is no way to mount the bracket flat and firm. The grommets give it a little cushion and flex, which eliminates the problematic paint chips and eventual rust that would happen under the bracket.

5/16", not 1/4".
I have a note somewhere that said 7/8" long with a 13/16" diameter head. It sounds like a step bolt without the square shank under the head. Slotted maybe?
I have the bolts and nuts used on the black and brass generators, 1912-14. The forward two use a longer runningboard bolt; the rearward two use a very short version of the same bolt. Both of these are made to the Ford prints.
What about the earlier bolts?
You mean for the all-brass generators?
Doesn't someone already make those?
Yes,RV A 1911
Here is what I made:
Here they are mounted on a dirty runningboard:
You can see the rubber grommet that I like to use under the bracket.
