What is the best way to trim and fit a Glaxo GS crystal? I've got one the packet says is for a Hamilton "Harris", but it lacks JUST A HAIR of fitting. Thanks in advance for your info.

sharp file,sand paper will do.

Thanks for the info Mr. Kasubski. I figured something like that would work, but I wanted to hear from someone on this site I was sure knew FAR more than myself. Thanks again.
