Dugly,
Everybody has given great intel Ill just add a couple of things
The 120-1051s are Dynalite II calipers with 1.75 bore for a .375 rotor with the standard Wilwood two piece bleed screws, not “speed bleeders”
The CA is the MFG date (in thinking mid 90s)
Everybody is on the money about pedal ratio being critically important.
I would say start at 7-1. If you have the travel, a higher P/R will never hurt you.
I am a fan of dual M/C systems too, but the change from OEM – to “race car” M/Cs is rarely simple and will require a fair amount of fabrication and development.
