Those kits are supposed to be generic moutning kits for several vehicles.
I own a couple of M151s (aka MUTT) and one has the kits mounted. It makes it a pain to get in and out of the vehicle quickly with a rifle in the mount, but its cool to drive around the back roads with your M1A or AR strapped in!
All those bags of screws and various styles of lockwashers are typical of anything government. I'd bet it's just a way the contractor can charge out the wazoo for the parts.
There are lots of extra mounting screws because there are several ways the kit fits onto a MUTT. First, if a ROPS (ROll Cage) is installed, the kit has to be mounted farther inboard. Additionally, on the drivers side, the light switch has to be recessed to allow the kit and the ROPPS to fit.
They're not difficult to install - uless you have a heater installed and then you have to be a contortionist or remove the heater to reach the behind the dash to hold the nuts/washers on.
You don't need instructions for the screws, just follow a couple of genreal rules that apply to military vehicle application of lockwashers. Remeber that the Star washer is used where there is likelyhood of water or debris. The stars on the outside will tend to not trap water and cause rust like the inside teethed washers. Also - the direction of the bolt shoudl be so that the threads are exposed to the least water/debris as possible. That means the the ones used to mount the butt plate bracket - th ebolts will be inserted from the bottom of the vehilcle.
There is a section on the back of TM, I believe it's the Direct Support manual, that goes over instalation. Although most of these manuals won't cover the provisions for the ROPPS adjustments, those are included in the ROPPS kits.
