Holes in back of cab

[John S-B]

Now that the bed is off of the truck, I noticed that there's a couple of what look to be splice plates on the back of the cab on either side. They're bolted on, but there's holes that obivously have never had a bolt through them as the paint is not worn at all. Where these holes for ventilation or was there an optional part that could be put on? I think there's 6-8 holes in each piece. I'm thinking of just pulling in some bolts just to fill the holes, one less way for bugs to get in.

They are probably the holes that are used with the convoy light poles. A "U" bolt should go through them to hold the pole in place.

If the holes are about 1/2" in diameter, and are about 3" on center, they may be for a ring mount for a cab-mounted machine gun. There would be one set on each side of the rear of the cab, close to the corners.

There are 4 main bolt holes for the cab reinforcement plate. I think the plate has something to do with a gun ring.

holes in a deuce cab? never!

They are there to let the wasps in and out of the cab.




(really, they are for the convoy light/antenna poles and gun ring legs)

Thanks guys, never was in a truck that used them. All the trucks in my old unit had the convoy lights mounted on the front of the cab. We didn't have gun mounts either, but we would open the passenger windshield all the way up and put an M-60 out the window over the hood during war games.

Don't you remember the lights I have on my deuce??? I was just there not that long ago!!

OF course we were busy with the whole putting a bed on top of my bed while I was there

Like said "U" bolts holding the pipe to the cab go through those holes.

Ya know I never even payed attention to those, I was busy trying to remember all the other cool ideas I was going to steal from you like those jerry can mounts on the rear mudflaps!!

They make very good mounts for a roof rack vertical support.

Thanks for asking the question John S-B, my deuce has the same thing. Now I am trying to figure out what is the best way to close them up so more rain won't get in. For now I just covered with black electrical tape

Love that ram air snorkel unclemikey! As well as all those other add on's I see in your pic..

Hmm, dug through my old photos, here is a shot from mine when I was mounting the convoy lights. You can see the upper U bolts on the poles. ( The 2nd photo shows how angle iron across the convoy light poles was joined with a second one and magically turned into a light bar. )

If all you want to do is close them up, easy.....then get some 3/8" or 1/2" bolts from the hardware store with nuts and washers and also look for the rubber washers like they use in the toilet tank to go on the bolts that hold the tank to the bowl..........take bolt slide on steel washer, then rubber washer put through the hole and put a nut on the inside.....the rubber washer will seal up the hole nice and water proof.......and easy to remove latter without damage if you ever want to use the holes.

I used a large fender washers on both sides, a nut and bolt with and sealant for the holes in the back of my cab.

Thanks guys, I was thinking of something along those lines.. I actually have enough room between the cab and the M105 bed to mount a Jerry Can in between. I have about 1-2" clearance between the can and the bed after I install it. I assume that would be enough for any articulation if I went off-roading or something.. I would think the axle would move more than the bed anyway..

Your thoughts?

 

[eagle4g63]

I know that there is an inch between my bed and the convoy lights and when I was at haspin I did rub the bed against the light poles, not hard enough to bend anything so you might be ok at 2 inches.

 

[DeucesWild11]

OK thanks, good to know. I don't plan on doing any off-roading any time soon but if I do I could just take the Jerry can off.. I think it will look good mounted behind the cab.. and I will at least use it to seal up one or two of the holes already there but may need to drill one more..

That's what I'm going to do.

Just do like one particular previous owner of one of my trucks did. Any unwanted holes he found, he just covered them with duck tape and spray painted OD over them. he closed up a lot of holes that way. It worked really well until I tried to mash the dimmer switch, which wasn there. ( the guy only had one leg and had no use for the switch) He just closed the hole and painted over it.
