Whats the size/tread of this master cilinder?
It came out of a F350.

I realize that one port is 3/8 and the other is 9/16. BUT, the thread is 9/16 - 18 or 20????

Do you have any part stores that you can just take the MC to and grab some fittings to try?

Unfortunatelly, no time time to take it away and try.

I`ve find this fittings in Ford F350 master cylinders:

3/8 24
9/16 18

7/16 24
9/16 18

3/8 24
7/16 24
