Who has installed the ultimate cup holder ?
 

I got two of these in and I am a bit puzzled......just slide the metal tab under ???

Yes. You may have to bend the top of the tab a bit to get a better fit.

I posted a pic in the other thread for you.

I didn't bend mine at all, they slip perfectly under the trim piece like what Mark T posted.

Yes, he did.....

I have one and it works great where Mark has it mounted.

Thanks Guys

I just have one of these from Autozone:
Bell/Door mount drink holder 05585-8 at AutoZone.com

The rubber flap goes under the trim and the horizontal bottom/base goes under the floor mat Works great!

I should add that I am not using at the window, but on the floor - like "the ultimate cup holder".
