If you are speaking of the clutch bell crank, rip it out and install clutch master cylinder and plumb it to slave. The only contest is to get you to explain better. You are taking the fact that we can not understand exactly what you are doing as an insult. We don't know what else a PO did. Stock bell crank? Bell crank for what? Stock steering box? Left or right side slave? I was thinking that by 1966 the bell housings were mechanical clutch , left side. But you seem to indicate you are using 1966 and want hydraulic, so I guess you know the bell housing is set up for juice clutch. At least in this guessing game, that's what it seems. If the housing is set up for Hydraulic it will have two holes near fork window for mounting a slave cylinder. Those are only "hints" not" advice". Stay calm John, some of us need to get to the point without worrying about dainty feelings....and as you can see are tying to help. Good day sir.
