My 48 year old clutch slave cylinder finally gave out. I bought a new one and when I went to install it I found that the threads for the hydraulic line were threaded in such a way that when it is tightened the cylinder is pointing 180 degrees out of line, the plunger is facing forward. If I try to tighten it or turn the cylinder to face to the rear, the rubber hose twists. Do I have the wrong part? Would a washer solve this?
