Does it have the Willys or Ford front crossmember?

I think the engine" sitting" around is the most likely. It is my
understanding that the reason all 3 numbers on the Fords match is that Ford
built and stamped engines at engine plants in MI and then shipped them to
Jeep plants around the country. When an engine was pulled and then put
into a chassis they stamped the engine number on the frame and then the DOD
tag was made to match. So, if your engine had new engine assemblies piled
in front of it just as it was about to be used or was shipped to a plant,
like say CA by rail, the ensuing week or so trip would put it well out of
synch with say # 3 or # 5, even though they were made minutes apart.
Willys' method of numbering the chassis, tossing in an unmatched engine and
stamping the DOD tag to match the chassis meant that MBs were built in
sequence but without 3 matching numbers, Fords method meant that all 3
numbers would match but that the serial numbers were not built in order or
all at one plant so the spread of engines, (and therefore VINs) was all
over the board, relative to delivery dates. I'm also not a GPW guy, so
every word of this may be wrong.

Why hold yourself to a higher standard than the rest of us?

Guess I should have read the whole thing first.
