#3 is Al’s clutch arm, right?
FWIW, I went the other way. I had a long arm and it was an exaggerated angle when I went to a hydraulic clutch, so I put a short one on it. I didn’t really notice any increase in effort. But I have a Spyder, and the hydro clutch eliminated the weird Rube Goldberg 180° pulley contraption that my car came with.
