Water Leak - Rear of cab

[TexasJH]

I have a large water leak, it's coming in under the rear window at the big square holes in the cab on the passenger side and drivers side between the cab and bed.

Previous owner had a speaker box installed and they covered the holes with some silver tape with thick black rubber, looks kind of like the stuff you put on the floor board to deaden the sound.

Anyways does anyone know what they factory uses to plug those holes, I thought it was a plastic grill of some sort and what is it called? I assume I can get a set at the dealer but I don't know what to call them. Thanks

These supposedly are vents that release air pressure when closing the doors. The vents in my truck leak bad. I need to figure something out.

There are two oval shaped grommets in the back of the cab that should be there. If they aren't you will definitely have a leak.

Yes, they are cab vents. It's common practice to remove these vents to allow for a speaker box behind the back seat. I would suggest going to the dealership and ordering new one's. If not, you can get some sheet aluminum and some body sealer(from a paint and body supply shop) and make a patch. DO NOT use silicone or any other type of household sealant. Good luck pal

I forgot to reply back, thanks for the help guys. I went to the dealer and they looked up the part number. Its $20 for the set. I took it to the body shop at the dealer and they pulled the bed, they installed the new ones for $50.
I tried for 3 nights to get the bed off but could not get 2 bolts out, I broke 3 bits, finally gave up and had the body shop do, they also broke 2 bits getting the bolt out.
