G744

Getting a "Book" for you truck is easy. That is, the military didn't really have different pubs for individual models unless they were VERY special.

The duece went thru three "Lifetimes", the gas era, the Muiltfuel, and the last "E3" variant with the Cat Diesel, auto trans, and super singles.

To the mechanics, all of the G742 series were the same, with a few differences owing to powerplant, transmission, bodies, winches, add-ons like heaters and fording kits, eTc. Commonality of basic components was one of the key design goals of all M-series trucks back then.

You can get by just fine with the -10, -20, and -35 series manuals. Those for the gassers are plentiful either as original surlpus on eBay or from Portrayal Press.

Generally as a rule, trying to get any DMV to change pedigree or year is a real uphill battle. I'd live with the paperwork as is and just get new dataplates done up with the right info and go from there. Who is going to care? Your rig is old enough to qualify as a historic rig in most states, and some (like Arizona) are exempt from all commercial requirements.
