Here's 2 more pictures of my second mount in the works. I took a drive with the first one and camera shakes are very minimal. I'm going to be adding rubber sleeves to the headrest using a hose of some sort so there's no metal to metal contact. I'm also going to try another camera mount because the one I currently have is too big and old school for my tastes. I'll try to keep this updated best I could.

Here's a sneak peek at #2.

Thick enough?

This bar's so strong it survived my mighty judo chop!
