Attenna Mount

[jbgroby]

I'm trying to mount the antenna to the P/S cowl and am finding it impossible to get the new antenna mount to hold. I bought it from LMC (which I'll assumes gets them from a far east country) In the pictures below which show the "crown" for lack of the proper name, when I tighten the top nut which compresses the crown downward it deforms the gasket/bushing to where it slips off the crown.

In order to attempt a quick fix, I roughed up the bottom of the crown with a dremel tool and put some crazy glue to hold the gasket in place, I'l see how this works later.

Anyone else have this happen?
