Snorkel Fixings

So I located the worst of my leaks this morning, seems I am missing a snorkel fixing and there is basically just a hole in my body work straight into the cab...

Can you buy the fixings and gaskets anywhere? Or does anybody have an old one? I can only seem to find the entire snorkel... although I assume any old nut and bolt and a gasket may do the job?

Photo required.
Why would part of the snorkel being missing mean you have a hole directly into the cab?

Will get a photo when I get home but basically at the top of the snorkel where it mounts to the windscreen frame, it is missing a fixture, so it’s only secured by one of the two fixings. Result of this is that there is a hole (approx 6-8mm) which goes into the cab through the frame.

Sorry probably wasn’tclear in my original post. It’s a fixing to hole the snorkel to the car

In the absence of a photo I am guessing that you mean large diameter tube-clamps like in the photos below?
If you are missing one of those then I guess that the snorkel itself may be a bit wobbly so yes it needs replacing but in the short term and to fill the hole in the windscreen-frame can't you just fit a nut / bolt / washer?

See attached, going to put a bolt but and rubber grommet on there for now if I can get a spanner in!

From what I can see it looks to be a Mantec plastic Jobby?
You just need a suitable nut / bolt / washer.
I would remove the bracket (give it a touch of paint at the same time), fit a gasket underneath and then bolt into position. Looks to me like the top fixing is a self-tapper but the lower one has been drilled all the way through to fit a nut / bolt so you will have to do the same.

Yeh giving it a go now - leaving the paint for now purely because rain is forecast and it’s leaking like a trooper. Very fiddly job though it seems... what should take 5 mins takes an hour lol...

Well solved one problem but found another as usual lol... got a bolt and gasket through the bottom hole, and this has sealed it seems... but the top one with the self tapper, the self tap fitting just pulled straight out. Looking at the inside there is no room what so ever to get a bolt through from the inside, or a nut....

Any ideas?? Can I get another self tap holder from anywhere? For now copious amounts of Vaseline around the self tapping bit has done the trick as it’s started raining again :-/

Aluminium tape will seal the hole well enough until you can solve the problem permanently. As for securing "pulled" self-tappers,either use a bigger one or a rivnut and machine screw? There are lots of other ways, but they come into the "bodge" category, like wrapping the old one with insulating tape to takeup the slack. My PO introduced me to that one...

Hmm a rivnut looks like it could work, just not sure if I have the clearance on the inside of the frame as generally only a little bit of it expands out correct? Unless that little bit is inside the frame it may not help?

I wondered about just body fillering the top hole and having it held on with the m8 bolt at the bottom...
