For example, in the Wilwood schematic if you flip the 2.67" and 4.00" your pedal ratio goes to about 9:1. Maybe I'm just not understanding the schematic/phots correctly. Have you had a chance to get a feel of the pedal yet?

Good catch! I had not considered that, but to my calculations, if that is the case, I can drop the pushrod position on the original pedal accordingly to drop the ratio. The numbers on the diagram are not mine, just a given example from Wilwood. But given the case, if the bellcrank ratio flipped is 0.66:1, and I drop the main pedal ratio to a 2.8:1 then I will achieve about 4.2:1. Which will still help with my operating angles, and give me a proper pedal. The truck isnt back together yet, so I wont know about pedal feel until Ive got it reassembled.
EDIT: I added a diagram of my unit, with my setup + measurements and how I calculated mine with my flipped assembly.
