Pedal ratio isn't to bad to figure out. Long side measurement (from pad center to pivot center) divided by short side measurement (pushrod pin center to pivot center) equals the ratio. '40 pedal picture as an example; 12 divided by 1.875 = 6.4 to 1 ratio.

Hey Rich! Guess what!? You were right, stating that the lower brake pedal had been welded and converted.

Very hard to see. Took someone that wasn't hard of hearing in one eye and couldn't piss out of the other eye, to look up in there to see where one of the welds wasn't completely blended in. Normal look up in there that pedal looks "factory"! Somebody did a nice job of converting that pedal.

Ok, measuring with my 6" machinest scale,,,,,,,, I'm partly guessing (because i am not looking straight on) there is 3 and 3/8" from the center of the pedal pivot to the center of the pin that goes through the MC rod clevis, or that hole in the bottom of the pedal. Am I making any sense?

So, if you do your "Jethro Bodine siphern", you know, ought into ought and carry five. What ratio do you come up with in corrlation with a 1" ID MC bore? What do I need, a bigger bore or smaller.? Thanks
