outside quarter window dew wipes for a convertible

I need to replace the outside dew wipes for the quarter windows on my 'vert. Can anyone tell me how to get the molding off that the dew wipes attaches too?

I have found one screw and one nut by the qarter window that holds the molding on, but I assume there are some other nuts or something holding down the rest of the molding that I haven't been able to find yet.

Any help will be greatly appreciated.

thanks
