My 1977 repu has a '80 rx7 transmission and today the slave cylinder took a dive on me. I was only able to find a 1981 slave locally but when I checked rock auto 1 of the slave cylinders have the same part # and some are different. Does anyone know for sure if a 81 slave will work before I go down there with my old one to compare?

 

they are different. pretty sure different pitch for the line. not sure what else might be different

 

Thanks Kent you saved me a trip. I just spoke to the P.O. and he has an extra one for an 80 hes gonna hook me up with.

 

It is the same **** but the inlet has a different thread pitch.
