Sport mirrors how do you pull them apart for painting?

How to disassemble the remote control assembly. First and most important, the 3 cables are, or were color marked and must go back in the same positions relative to the locating tang so the mirror moves in correct directions. Make new marking, take pictures, whatever.
You'll need to fashion a jig with a small C clamp and a small piece of tubing over the wand to compress the tension spring without bending/damaging the wand.
The cable sheathes are spiral wound so they will screw right out of the crimps like any threaded hardware ( a drop of 3 in 1 machine oil could help ). Now the cable itself will come out of the lower crimps gap ( whittle to widen that gap only as much as needed ). Any bending/prying will break the crimped pot metal material so just don't.
Push/pull the ferrules crimped on the cable ends upward and out, again whittling those gaps only enough to remove the cable. Beyond the C clamp fixture I needed a dental pic and utility razor.
The only "tricky" part was pre or back twisting the sheathe the correct number of turns so it screws back into that lower crimp to original full depth. I think I used a very small needle nose vise grip parallel to the sheathe ( its been a while ).
A heat gun will melt the adhesive bonding the glass to the metal.
