just for the record, where did you get it from?
• 'red' is 3/4 piston
• 'green' is 11/16 piston
Color isn't 100% anymore - my last one was 3/4" and gold, I'd expect yours here is 11/16".
I put in an aftermarket unit once where the line into the slave was moved to the other side. I didn't know to look then but bet it was 11/16... If you buy a unit and see the line's on the 'wrong' side, I'd not use it. I had a heckofa time adjusting it in, and it failed in
