When I moved my pivot point to give me a 4.7-1 ratio vs the 1.8-1 ratio they had set, I discovered that the 5/8" cylinder they had installed would not release the bearing enough. Reason being was that cylinder has a 1.4" travel. Having the pivot point where it needs to be only gives me a 1" travel. So I put the 3/4" cylinder back in because it has a 1" travel. Works like a charm. Pedal effort is easy as pie now. So it proves that pedal ratio plays a greater role than cylinder size.
Here is the photos I have right now.
I used a McLeod RST clutch and 1400 series bearing.
Mounted the reservoir up by master cylinder for the brakes.
My Swiss cheese firewall, the way I found it when I started to make my own mods.
So after some thought, I had my local machine shop with their fancy water jet machine cut me a plate using the steering column holes for support which strengthened everything up. I just had to fab up a card board template. As well I notched the top corner of the cylinder block so it clears the column bracket on the firewall.
First test fit on the linkage shows that I had to use bolts with slimmer heads on them. Otherwise the clutch and the brake hit each other.
I spent 3 hours re-wiring and routing wires over clutch and brake bracket. Frustrating, but well worth the time and effort. As well I moved the D/S vent cable and ran it through a hole in the clutch/brake bracket above pedals. This way it lined up perfect with the pivot on the vent. These details shouldn't be overlooked on build as you want to make things as safe and reliable as possible.
After adding and subtracting washers to get my spacing correct. My travel is full through complete clutch pedal movement. The rod clears fine on both sides and the new bolts on the clutch eye and brake have a good 1/4" space between them now.
Topped off the cylinder mount with round allen head screws, so there is no contact anywhere on the rod. I also put jam nuts at the end of the eye and both ends of the coupling link. Much safer now!
Adjusted brake light switch and tied wires up nice. Now that is all you see for wires.
