Bottom is most likely something like HQ or HHC or it looks like the 522nd Engineer Company was assigned to the 194th so it could be ENG. The 107 at the end would represent the vehicles "Order of March" which is what number it is in the unit.
You can also check by sanding on the lower rear of the tailgate as sometimes they were added there instead of the bumperettes.
