I would go back to RAM MOUNT again and re-look. I have a mount from them that has 4 or 5 way positioning and there is no ball and each position can be locked into place. They have pages and pages of stuff. I remember it took a while to figure out which pieces we needed to make up what we have, and have it work for us. Prices were resonable enough, and we worked with a good company out of GA.
