The Bendix change-over year was 1951 (for the 3100) , larger trucks changed over later.
What year do you have?
What parts do you want in the "kit".
Most likely, the following separate "rebuild kits" are available (depending on year and size of true):
- wheel cylinder (front and rear are different)
- master cylinder
- hold-down/install hardware (maybe)
- drums (maybe)
