I put a hydraulic setup on my bronco. It works great. I used the wilwood ***** cylinder and wilwood clutch master cylinder from Summit. here are the part numbers.
WIL-260-1304 Master Cylinder
WIL-260-1333 ***** Cylinder. 1 3/8" stroke.
Both work great together. Here are some picture of it installed while the body was off.
Use the hole for the speedometer cable to mount the master cylinder. Just enlarge it all little and drill the two mounting holes. Drill 5/16" hole in your clutch pedal and use a spherical rod end to connect the master cylinder rod to the clutch pedal. it is a clean installation. I will take some more detailed pictures and post them.
