hey, how the heck does this antennae bezel come off?
Im pretty sure youve taken a few off and hope you can enlighten me.
A total whrench head and I cannot for the life o me figure this one out.
I dont have a spanner wrech so I lightly tapped on the (what appears to be) spanner nut and nothing.. Ill torque the fender if I tap any harder...
is there something underneath? what am i missing?
THANKS
