dont quote me on this until i double check, but they are napa pn. 641-3183. they cross to a dodge 3500 4x4 or something. i just pilfered through the book one day untll i found a stud with the correct thread, correct knurl diameter, and depth. then i matched what i needed based on the factory ford stud spec and the difference now that there is no rotor hat in between. these were perfect if a few thou bigger on the knurl

Im wondering if the brake pedal should put a bit of preload on the master or if the plunger should just touch the piston with no play ? My travel is limited just a touch because of the old under floor style pedal and master . If I could preload the master a bit that whould help for sure with the travel.

i dont think i would pre load the master so far as to apply it. if it was set up static at that piston depth it would not drag the brakes, but it would not have the correct stroke for the circuit. i think it would actually diminish the braking pressure. i dont know this for sure. its been a long time since i studied MC fluid circuits.

you have a regular truck farm growing over there! i picked the key up from a local tool truck guy. it was just hanging out on the shelf and i tweaked out and bought it. just for the size of the thing. then i got inside and realized that it was perfect for king pins. best impulse buy ever.
