As I understand deflector was an option, not sure if it was available after 89 when they started putting rear wipers on.
Anyway, my 88 doesn’t have it and every now and then I’m thinking about getting and installing one. It should help blowing off water off tailgate window when driving in the rain, and probably allow driving with window a bit down without sucking exhaust fumes in? What stops me is that it costs a lot and I’m not really comfortable with drilling holes in good roof that doesn’t leak
What do you guys think?

Their main purpose was to allow you to drive with the window down and now pull exhaust into the cab. If you don't plan on driving with the window down, don't worry about it.
Oh, that sucks. I was hoping that it’ll help with rain all over the rear window, when it rains I can’t see anything. Doesn’t trouble me that much and I don’t really care about driving with window down. Guess that’s some money and roof drilling saved!

It could help some with that. But would probably be speed dependent.
It helps somewhat with the dust as we could observe in some of our outings in large expanse of loose sand -aka black rock desert-
The OEM deflector is held up with the same well nuts as the roof rack, so you need to drill/punch large holes, and the rear most are almost blind because of the roof structure of the support beam
the non plugged holes are for the deflector

Old thread here, but if anyone is still looking at it, could you possibly let me know the size of the holes I need to drill/punch to mount the deflector?
I just picked up an 88 GW and it already has holes where I need to mount the deflector. But for some reason they are much smaller then the grommets I got from Team Grand Wagoneer, that I also used to tidy up the roof rail mountings.
I can take off the roof rails again, and measure the holes, but would rather not risk loosening the grommets if anyone can tell me hole diameter that's needed.
Many thanks!!
