Bob, Shouldn't the "motor mount" have rubber gaskets top and bottom?

Assuming you are referring to the darker green filler between frame rail flange and transfer case mounting bracket, the one I removed from the water truck frame certainly didn't, it was rigidly mounted.
The dark green filler has different bolt spacing than either radiator or motor mount. We had to shave it down to fit in place as it was, no rubber would have fit.
The transfer case to bracket and cross member mountings should have either "tire casing" or steel spacers about 3/16" thick depending on early or late production. Bob dutifully sacrificed a virgin (tire casing, not re-capped) to put rubber spacers in place. Most current casings have fewer cord plies than their rating so are squidgier than 1940s casings when cut. (rubber isolator bolts torqued 35 ft-lb, steel 110, also different styles of securing against vibration)
We did look at the HUP to see what it had and noticed that there were full motor mount style isolators at both transfer case to cross member and frame bracket. Another case of HUP is different than other CMPs???? Bob's "near rigid" mount is typical of the field trucks and matches the C15A manuals.
