We may have to move the rearview passenger mirror on our 2004 Fleetwood Excursion to get it in the pole barn. Right now we are off a couple feet of getting her in

Wondering if you just loosen the set screws or is there more involved than that. Don't want to mess up the wiring.
This is how we ended up and that is not going to work with winter setting in. May have to bump out the back end of the barn.
