Can't find manual gearbox breather

Hey guys
After changing my transfer case and gearbox oils last weekend (there was water in the gearbox oil) I went looking for the breathers to extend. The transfer case one is really obvious - right beside the shifter, but I can't find the gearbox one. I have considered it may be the two metal caps I can see on either side of the bottom of the shifter.
Also is there much point actually extending these breathers - will water just seep in around the shifters? My transfer case rubber sealing boot is in good condition but the gearbox one is munted and certainly does not seal around the shifter any more.
Thanks

yes the gearbox is a cap, the system is a good idea however the flaw with the caps is when they are underwater the caps float allowing water to enter. i am in the process of extending mine. the gearbox shifter is a wierd set up mine had water sitting under shifter but it cant get into box i dont think.
perhaps someone could post a picture for him?

yeah a pic would be great, I can probably take one and point out what I think it might be if no one has one handy though. There are 2 metal caps on on either side of the shifter - completely covered in grease and dirt at the moment though.
Or does it look the same as the transfer case one - in which case I havent found it yet

Mu is slightly different in that the shifter is on an extension which the bighorn isnt

it should be another cap, one cap on pass side and one on drivers side right by gear lever just past transfer lever

Yeah thats what I was thinking was probably it the two metal caps. I am yet to pop the caps off and look at what is underneath and they are totally covered in grease and baked on mud, fun fun!
Thanks

Anyone know if these caps pop or screw off? I have had no luck with prying or twisting forces, but they aren't the easiest to get at. I am reluctant to use excessive force, in the event I pop off a cap and see that putting a tube over it and running a breather to the engine bay is not possible and then I have to reuse the munted cap.
Shifting is getting harder so I suspect there is lots of water in the box.
Cheers
