Master Cylinder Ports on 89

[sperold]

89 SHO (no ABS), what ports on the MC do what?
My 2 front-to-back lines failed and I have not had much luck pinching them off (long story) so that I can run the car up on the ramps.
I decided to plug the ports on the master cylinder, but which ones?
Thanks.

What is it that you are asking? I replaced my booster 2 years ago and cleaned the heck out of my master cylinder. The 4 ports that I am thinking of are for the 4 brake lines. I think there are also 2 ports that connect to the fluid holder.
