Hi Kenny,
One thing to remember when working on one of these old Willys.
If it's been through a few owners, the odds are good it has become, to one extent or another, a Jeep Salad.
Because so many parts were interchangeable between years and models, many of our Willys have acquired parts from other Willys vehicles, not just other CJs.
My '54 3B has an engine, and probably transmission, from a Truck. Serial number is late '53. Most POs weren't very concerned with "year and model correct" repairs. They just used what they could lay hands on cheap.
My buddy John's stake bed Truck is actually a Salad put together with parts from 1951 through the early 1960s. Makes it interesting to find matching parts. Which portion of the Truck do you try to match?

It's all part of the fun.
