Hy Lozzyuk, welcome, could you tell us the bore of the brake side of your dual master cylinder? If the brake side bore is 1 1/8" then Raybestos p/n MC34404 is the correct dual master, that is available at RockAuto $46.79 plus shipping. If the brake side bore is 1 1/4" then Raybestos p/n MC19089 is the correct dual master, that is available at RockAuto $183.79 plus shipping. I have no idea why the vast difference in pricing, hope that helps.
