Thanks Bill. I have looked at your site before, very nice!
Went to dads last night removed the MC, as it turns out it was missing one screw and retainer off the back of it that holds the pistons in, and the one retainer was bent, so it allowed the piston to start to come out the back. Fabbed up another retainer/screw, put it back in and bled all the brakes with new DOT 5 synthetic. Cross your fingers.....
