Bore size sets pedal effort and travel, so match it to your system rather than to a number you saw on another build. Mount flange spacing covers 3.22 to 3.40 inches, the common measurement for most domestic cars and trucks from the mid 1960s to the present. Wilwood also offers a combination proportioning valve kit with brackets and stainless lines built for these master cylinders.

Fitment: this is a universal chassis component sold by bore size and finish, not by vehicle. Confirm your mount flange spacing, pushrod requirement, and port sizes before ordering.
