I guess the only way to know this spec is to have a truck with the system already mocked up and in place. Not sure if you have this or not, but figured once these kits get out and in circulation someone could provide this to help everyone order the right master cylinder for their particular throwout bearing. I noticed your ad states that the kit includes a master cylinder properly sized for the buyer's application, so I assume you offer different sizes of the Wilwood units in your kit besides the 3/4"?
