Hello. I just recently purchased a 1967 Datsun 411 station wagon the 4 door sedan. Does anyone know of a clutch slave cylinder that will fit this model from other models? A buddy of mine and I were trynna clear the air from the lines and adjust it for the time being but it did something unfortunately. I came back a few days and the fluid was all drained. We broke a seal or something. Any suggestions or maybe what models fit the same clutch slave cylinder. Thank you!
