You can take the two screws out of the inside - the ones holding the mirror swivel assembly in place, then the mirror and swivel with cable can be feed out some. You can't get it all the way out due to the way the cables are crimped at the ends.
Each cable end should be color coded with a daub of paint (might be faded / dirty). Ferrules at the ends slip into a notch and all are held in place with a small (but strong) spring -- don't lose the spring! I would recommend placing fresh color code on each cable end to make re-assembly easier. Try not to break anything since as I recall the swivel housing is pot-metal.
OK - not having any luck. Tried the way you said . The ends are tuck under the center below the knob where my pick is at. See pic. I'm unable to get the end out from there. Looks like I need to remove the knob and push them out if the center hole goes through. The knob is tight and I'm afraid I will brake it if I twist any harder.Okay, had to take a new picture. Here we are looking at the 3 ends where the knob goes. The ferrules are most likely stuck in their grooves so you gotta be patient and start with one of the 3 cables that is NOT getting pulled on (depending how your swivel sits, if that makes sense). You can use some needle nose pliers by grabbing one wire and gently pulling on it while pushing the swivel towards the cable you're working on. My ferrules weren't color coded and it does not matter how you are putting it back together! Hope this helps!
Do NOT try to pry on it, you will break it! If I remember correctly I pulled on the protective springs (these are like sleeves and they move) looking outer part of the actual wires, try to pull on them one at a time and as soon as you get the first one off the others will come off a lot easier than the first one. While pulling you can try to move the adjuster, you will get it out!Oops - Forgot pictures.
