Wilwood master cylinder with pentroofs, fitment in 67 Fairlane?

[6667fan]

I searched threads here for Wilwood masters and did not see what I need to know. How does their master cylinder fit in a 67 with pentroofs? Car has a 15/16” bore Ranger m/c currently and stops for sh#t. Might try 7/8”. Factory disc set-up with 2.5” drums out back. No booster.
Speaking with Wilwood tech they suggested 7/8” might be the way for me to go. I will confirm my pedal ratio of course but the last time I measured it I thought it was reasonable. 

Thanks,

It fits but its close, luckily the wilwood arm is ball that pivot's so I have a spacer to push it to the side. Stops fine, I do not notice it at all when braking.

Thanks for responding plus bonus pic. Are you saying the arm that attaches to the brake pedal has a heim joint which allows for some flexibility when the master is cocked? I have the Ranger one shimmed currently.
