Dyna turn signal info
For Wide Glide & Fat Bob models: 06 and newer bikes do not require turn signal relocation.   Rear turn signals must be relocated to rear most hole of fender strut on 05 and older Wide Glides.  This can be done with HD relocation kit #68734-02 for 2002 - 2005 bikes, or you can use the #2305 Kuryakyn turn signal.  Pre 02 models must use the Kuryakyn #2305 or other aftermarket kit as the Harley kit for these bikes has been discontinued.  The Kuryakyn turn signal is smaller and gives you more room to get into the detachable pouches if you mount them on the rear of the saddlebags.
All other Dyna models:  If turn signals are not mounted to the license plate bracket like they are on Dyna Convertibles, they need to be moved to there.  This can be done with HD kit #68512-89 for 2001 and older bikes or HD kit #68732-02 for 2002 and newer bikes.  These kits look like the photo below on the left.  A better option is to use one of Harley Davidson's layback license plate/ turn signal kits, pictured below on the right.  These kits use your existing bulb housings and work great.  For 2002 and newer bikes us # 60215-06 and use # 60134-01 for 1994 -2001 model bikes.
