Looking to get a service manual set for Big Ugly and have two options basically: 1. military CUCV service manuals. There seem to be several, I've heard they can be rather complex, and I'm having trouble locating them in paper form. Lots of them on CD if I choose to go that route. 2. Genuine 1986 Chevy FSM set. I know where there's a set but dunno if it's worth my time and money to get them since the CUCV's are somewhat different. I guess a third option could be both. Any of you CUCV guys gone through this?
