I need to buy some fairing fasteners for the RC51 fairings I just got to attach the lower to the upper...

I see there are a few different kinds out there, but I've never used anything other than stock bolt style ones.

Anybody got any suggestions on what to use? I'll be running 3 per side. Just to fasten the upper to lower. I will probably be running a mounting point down below to like my Sharkskinz has
