well, yes... lol... I'm convinced that most of the problems out there related to cores dropping/dies activating, is a simple contact problem. This could surely help as a solution, opposed to attempting to shorten spacers thru dis-assembly & modifying hardware, and risking screwing things up.
this is a simple & quick way to cure it.  I was faced with this problem on a saturn, which had a stripped screw from assembly, and couldn't really be fixed without tearing it apart. I was able to get some pliers in there to turn it a bit, but it didnt last for long, because the threads are stripped. The pad trick worked.
Yet another Sat had similar woes, but no stripped screw. The pad trick worked there too
