HOLES IN ROOF, How many do you Have?

[iLikeEggs]

I have two radio NMO mounts which I kept for ham and GMRS antennas. There was also an access hole towards the front for the lightbar cables. That was plugged and siliconed.
They did a decent job with that one but it was ugly. I found a fake shark fin stick on antenna on ebay for about four bucks and used that to cover it. Looks pretty factory now. It's been on there almost two years and no problems.
If you have the NMO mounts with no antennas still on the roof, order the TRAM NMO rain caps. They are cheap on ebay. They have the rubber o-ring so it seals it up tight and looks professional. They also sell them in ham radio shops if one is local.

I've never even paid much attention to my roof until I read your thread, great topic.

I actually just have one hole in my roof, oriented more towards the passenger side above the front passengers left shoulder. I assume it was for a 800mHz antenna, but not 100% sure. Glad to know I had a 'slick top' truck (less holes). It appears the hole was drilled at a size for an appropriate hard rubber plug, that is sealed in place. No worries, whew!

That hole is most likely for the light bar, open up your doors stand on the running board, look behind the rubber seal in the rain gutter, there should be two holes on each side which held the light bar.

When we down fit our FD Suburbans, they will have 10 holes in the roof from antennas and the light bar mountings. Additionally, there will be holes in the fenders, tail gate doors and rear bumper cover.

So if you take a three inch hose and fill the truck with water you would basically have a large lawn sprinkler?

Has anyone considered getting a entire roof vinyl that will cover all of the hole plugs?

Wrapping the roof would be a great way to seal/cover it up. Would be easy on black anyway. Might look good in a matte finish.

Thanks for the reply, I haven't decided on a color for the vinyl yet. I am still leaning towards a gloss white vinyl so it keeps everything well hidden.

My truck came with 5 holes - 2 running down the middle, 2 at the rear and one by the front passenger for the light bar.

There's an ebay seller with plugs that work perfectly for covering these holes:

Thanks Cobra - Going to try those plugs. Looks like
a nice assortment:

2 in roof ( currently stuffed with silicone )
1 small one on dash ( former light switch )
1 x 3/4" in inner liftgate panel

Glad to help. I put a tiny ring of silicon around the hole then, then installed these making sure that no silicone spilled outside of the plug. They install cleanly and blend into the body.

I used to have two, well technically there are two (and there were the ones, factory, for the luggage rack.

One I re-used for putting a GPS antenna in, used a brass ring/nut with an o-ring and a cap to seal it (drilled a hole in the cap for the wire. Sealed it up, and put a shark fine over it. The other hole I re-used for a CB/Ham radio setup with one of those Motorola mounts .. when not using it, I put a (Motorola low profile) rain cap on it.

The factory luggage rack holes, I put to use by installing a luggage rack. The OEM dealer one is almost $900 in parts, a salvage yard one, compete was $150 plus a few bucks for the riv nuts (the factory riv-nuts actually have a sealant on the outside, and the bolts to be used do too)and a tool to install them properly.

I have the impression that nothing much was done after it came from the factory. I only found one spot where 3 wires were cut, in one harness that was spliced into the distribution box, near the brake pedal) Looks like they were for some sort of radio. I found that when hooking the speed sensor up to the GM Navigation Radio

We had just a little rain/snow around here, but I think I fixed it properly.

3, 2 antennas, and one lightbar wire hole. NJSP is lazy and instead of doing their antennas down the middle they just mount them on each side. Reusing the two antenna holes for my own antennas so all worked out.
