If your replacing your Stock Mirrors you will have to replace your Turn Signals as well,

Harley has a longer threaded Mirror Stem than Custom Mirror's on the market, the Turn Signals are threaded on the bottom of your Stock Mirror Stems, so when you Replace your Stock Mirror's with Custom Mirrors they will not fit back where your Stock Mirrors went.

So you will have to go with another type re-location of the Turn Signals that we have available on our Turn Signal Page.
