OK, so with great help from Diamondback and RetSUBLDO I got the new dash pad Garmin mount on my 2009 Ultra and WOW! To start, here is a before picture with the 660 mounted on a TechMount off the bars;
Here is the parts listing again;
1106 Screw
1107 Screw
7686 Locknuts (2)
92346-10 Mount (accepts garmin cradle)
92466-10 Retainer (goes inside fairing for support)
57885-10 Pad (dashpad specific to cradle mount, already has holes)
After removing the shield, fairing, and stock dash pad you need remove the chrome trim off the dash pad and put it on the new pad. I found it helped to get the holes lined up on the new pad to put one end on the workbench and push gently down like you were trying to bend it like a bow.
Next you will want to tape up the area that we will be drilling, even though you will be drilling from the back through to the inside of the fairing. This keeps the paint chipping risk to a minimum
