2 3/8 is correct, I have found that with my tower anything that I have mounted including mirror and speakers I used 2 1/2 clamps and rubber gasket. This holds better than metal to metal and doesn't damage the tower cosmetics. Not sure if that was what you ultimately were asking but thought I would offer it up.

Yea we call them a cheater tower. They are pretty nice for landings. Easier on the shoulders and elbows. I have ridden behind them. I can't say they help with "more air" that much. So people swear by them, I personally didn't notice that much difference. They do look cool though. They had one for sale on the Hydrofoil Forums for around $600 about 2 months ago. It may still be available.
