Seth spotted this hard to find part.
“This is a used bilge pump and propeller shaft PTO for a Ford GPA Amphibious Jeep. If you are lucky enough to own a GPA you know how rare these are. Both levers shift in an out just fine. The levers have casting #’s of GPA 1548 and GPA 7248. The number on the housing is 7 38 1. Great item to have as a spare or if you are missing the PTO this is your chance to help complete your GPA. This PTO has been sitting on the shelf for over 40 years. Please look at the pictures to make sure this is what your looking for.”
