Extreme tower mirror

[willyt]

So my mirror fell off while towing last week... the mirror landed in the boat but the big circular nut that the mirror attaches is nowhere to be found. any idea where i could find that hardware?

I would just poke around at a hardware store. Im sure the thread is standard, like a 3/16 or 1/4". You will need to take the mirror with you. But I have seen plastic thumb nuts/wing nuts available.

Or for $59 at Walmart, just get a new mirror, then you have spare for next time your mirror falls and doesnt make it in the boat.
