    Have you tried Pacbrake.com. They have parts and tune-up kits for the old Jakes.
    Years ago Jacobs updated the parts in the tune-up kits and merged all of the 25B, 30, 30E, 400, and 400H all together to use the same kit. Under #3871418.
    Pacbrake lists them under P40024. This includes 425A.
