Looks and works terrific. BUT you have to have rod cut in order to work and realize you'll have to run new brake lines.

If your dual master cylinder has a deep push button the pushrod may be 1" too short. I fabricate and overcame the situation for my deep rod button. Used on my 1959 GMC 100 pickup.
