I don't think it's going to work but you never know..
towards the base it's 1.5 and it narrows a but not quite enough for your clamp it seems
the middle is around 1.4 inches and the top dosen't seem to have enough lip for anything to grab on to. It was hard to photograph because I had to use my phone's direct flash..
Perhaps you can try it out at your dealership on a demo car?
Did you get the Ram a can or suction cup end?
