Master cylinder question? What's it fit?

O.K. I get it, your not smart enough to look at the back and put a ruler across the hole and see if it is 1", 1 1/8" to find what you ask for, you ask for the application for this master cylinder. And you dog me for going out of my way to try to help you, what a A$$. I'm done.

Good, go away, stay away.
Don't need your input.
I should have kept my fingers off the keyboard from the get go, and just advertised it in the for sale section.
