I’ve got a 2500 base model and I’d like to put power mirrors on it does any know a good route to go I’ve tried finding factory switches can’t really find them I’ve found the mirrors just can’t seem to find anything else has anyone else done this??

Was in process of replacing factory hitch. The 21 mm bolt that runs through the hitch, bumper bracket & bottom side of frame rail were seized up. So they got the cutting torch. Now I need to replace the 21 mm bolt & the weldnut/capture nut. Cannot find anything out there on this. Does anyone...

Anyone else have a problem with their armrest coming loose? Its been loose and now just falls to the seat when folded down. Can't figure out how to tighten it because the leather doesn't have a way to come off. Anyone have any ideas?
