Reversing mirrors on FXBB 2018
 

Hello old chap, from somewhere not so far away. As your bike is a Softail I recommend you ask over in the Softail section, where you may find someone with the same bike who can help. In the meantime, you will find that there is no substitue for getting the genuine factory service manual, for working on your bike, which should show how the mirrors and lights are set up.. Your local dealer can supply.
