The postwar Universal Jeep maintenance manuals and the TM-10-1513
(all written by Willys) show what Chaz and I are saying. This is correct.

This is consistent with what Chaz an I are saying. The engine sides are
usually designated as looking at the engine from the rear. So this
is the right side of the engine.

The offset is also away from the nearest main bearing.

This is also correct. Slot of the piston faces the valve side of the engine.
Oil spray hole opposite the cam. Offset of the connecting rod is away
from the nearest main bearing.

This is correct.

I think what you are confused about is the definition of an offset. When
the offset is correct, the larger of the 2 distances on the "big end" of the
connecting rod is opposite the nearest main bearing. This distance is the
area between the connecting rod "center" and the end of the "big end".
(When on the crank, it is the distance between the crank and the center
of the connecting rod.) The postwar Universal Jeep maintenance manuals
have a nice picture showing you what the offset is. By using this definition,
the statements in TM9-1803A and the picture in TM-10-1186 are consistent....
