This may not apply to too many people, but thought I would share just in case.
Thanks to the Forum, I figured out how to remove the Headrests. I want to use this Pet Barrier;
BTW, it's brand new and won't be available for about a week. If you need one right away, they make this one also;
And no, I don't work for them or have anything to do with them, I just like the design.
Problem is, to use either Barrier, you need 1" (K9K) or 1 1/4" (Walky Guard) of Headrest "stem" to attach them to.
In the stock configuration, the rear Headrests on the Nox only allow about 1/2" of "stem".
When you remove the Headrests, you will see the little grooves cut into the stem that lock the Headrest into position. I measured down 3/4" and made a mark. So what this does is to raise the Headrest 3/4" and that, in combination with the 1/2" you already have, gives you 1 1/4" of "stem" to attach to.
Pay no attention to the other mark you can see, initially I was going to cut down farther, but decided I didn't need to go that far.
New groove cut 3/4" from the original groove;
Ends up looking like this;
To me, having the Headrest 3/4" higher than stock isn't noticeable and now I've got the clearance to use the Pet Barrier.
DISCLAIMER***Because this involves the Headrest, I feel I should mention that I don't think this will have any effect on safety, but I'm not an engineer and if you decide to do this, it's at your own risk.
