The BT66 has the flat pieces on the ends doesn't it? Like the 2 bottom ones in the pic.

 

Flat actually all the way around with upturned edge. Just wider at sides.
the upturned edge is what holds it in place. Like a wedge fit. Prolly why it doesn’t last or stay put. Not a lot of contact space.
the Velcro solved my issues.

 

The very bottom one in the pic is the one I had.

 

Yup that's the reason I suggest the BT68 regardless as to whether you have the chrome trim or not. It seals around the edge of the entire opening in the fairing. The BT68 is the one on the top in the pic I posted earlier.

 

Seems like BT stop selling this. I clicked the link and you get this.... also went to their website via new tab and get the same results... dang shame considering i just ordered the MEX-GS620BT...
What to do now i wonder?

 

I would make a phone call and inquire about them.

 

BT supplier retired and they haven't found one yet. SBates could you put the word out since your one of the forum gurus.... Sucks for us that dont have one
