I need to get a master cylinder rebuild kit for my 1970 C50. it is a duel resivor type with a hydrovac under the cab. can't find any #'s on it and parts stores are having a hard time finding a listing. I am also replacing the lines down from it but it has 2 rubber lines on the frame just down from the master. can't find these any where either. I thought of just making a loop of line after the master to take up shock and eliminating the hoses. what do you think??
