Gravity mount windshield and dashboard - flexible gooseneck

I got this for myself and got it for $24.95. MISSING PIECE: the sticky part for the bottom of the mount is missing. Lots of people can get it on Amazon and they have a pack of them! I had opened it and I put my phone on it but I have a pop socket so it didn’t fit. Other phones like apple, galaxy and most smartphones are good!! I just have a pop socket it, so it just sucks! It is 3.25 wide.
