When I rebuilt the box in my '42 2 years ago, I called Chevy Duty to find out who did their box rebuilds. His name is Tom Woods and he is in Texas. One of the nicest guys you'll ever meet. It is really easy to do, and I found that by removing he parts, I could use the part numbers and the NAPA store could get them for me. His number is 214-284-4244.
