BEFORE YOU ORDER: You must dismantle your master cylinder and measure height of 1 of 3 shorter seals. For this kit you need your shorter seal to be 5mm or 3/16" in height. You get 4 rubber seals, and 2 aluminum union washers, and 2 copper washers and a new snap ring plus an exploded view & instruction sheets of best practices in rebuilding the master cylinder.
