That similar type of mount was used on the ford big trucks for quite a few years I think, Like Alchemy says, a number would sort it out
brake pedal pulls... mechanical brakes... pre 1939... part # starts with 81... memory says that is 1938...
81A prefix indicates '38 car, but '38 car and pickup pedals are same as '37, so the pedals would have a 78- prefix. The '39 car and pickup pedals should have a 91A prefix. '39 big truck would have a 91T prefix.
There you go, 1938 big truck. I knew it was before the hydraulics started, otherwise the brake master cylinder actuator arm would have pointed down.
