Master cylinder question? What's it fit?

To I.D. a master cyl you have to know the bore size! One thing for some reason you refuse to tell, I have old Wagner catalogs that have applications and bore sizes per vehicle, that is the only way to I.D. them. Sorry if you can't understand that! You were the one that ask for help I was just trying to help but I can't with out the correct info. It is very simple you are the one making it hard.
