These are the absolute best quality plugs around and Fit all street glides from 2006 to 2013 not 2014+ years
This set of four plugs fit in place in the stock mirror holes. will work on evey pre 2014 bike but may need small adjustment or a small dab of glue

If you are upgrading handlebars or just just getting rid of those stock street glide mirrors theses plugs are a must have. 
*BE AWARE* : not all harley mirror holes are the same some times the plug may be to tight and you may need to open it a little bit other times the hole may be a little big where you may need a dab of glue and some times it will fit perfectly
