Zenith Microtouch 2G needle issue

[Electronic M]

Those screws don't thread to what holds it, but they are connected to what holds it...The changer is meant to be floating when in use.

There are clips below the threaded portion of the screw. Those clips are meant to be flipped into a position where the changer can be easily be lifted out. With these types of clips on a changer there is ALWAYS a way to get at the under side of the installed changer to flip those clips into the removal position. Don not force it!...If you do you will break those clips and the changer won't have anything to hold it in later.
