Ok replacing the wood on the running boards and Langs has them for the RB brackets, a set of 4. This original Dec 23 roadster also has a block where the rear fender bolts to the running board but my June 24 touring does not.....it's was restored in the 70's by my Farther. Langs does not list one for anything later than 1916. The thickness seams to be the same with only the length and bolt hole spacing longer.

Your car only has flat washers the size of a quarter between the running board and fender. In late '24, Ford started putting in a dimpled washer as part of the fender, so you don't need the washer any more.
