They're talking about the chrome covers that are on the left and right side of my license plate. They're magnetic and cover the ugly mounting hardware for tourpacks and luggage racks. I hope this helps

 

I have an 11 SG and the book says two large and two small but I bought 4 large by mistake but they seem to be right for the 4 point mounting system, the short ones don't seem to be long enough to cover the black grommet....

 

Nevermind I looked them up.

 

2010 catalog says 4 small for my 2010 Street Glide

 

They are only $25 at the dealer. The pack is easy to open (and close) and they let me try each. My 2010 RG took the large size.

 

those look huge, not for me

 

raceface-that is exactly what my docking hardware looks like, do u recall if you have large or small or both? Thanks

 

All four of mine are the same. Little less that 1" in diameter and about 1" deep.

 

Ther is a chart in the P&A catalog that will tell you what size(s) you need.

 

The catalog has conflicting information, and I didn't trust it calling out 2 different sizes. I have 4 of the same size on mine and they fit as I'd expect. I think the up to 08 bikes take the staggered sizes, while the 09-up bikes use the same size (large) for all 4.
