I've posted here once and am a new rider with only basic bicycle experience.

I recently got a used Trek 520, it looks like an '84 from the research I have done, from a church resale shop. Picked it up for a rather inexpensive price. Trouble is I recently stripped the stem where the single bolt that tightened the handle bars inserted. So I checked with my LBS and I will need a new stem. They measured it at 22.2. They are a small shop and only had one similar stem in stock that had a raise instead of a drop to it. I've looked up all I can about, threaded quill and threadless stems. I already removed the old stem without much trouble and am looking to get into my own bike maintenance by buying and installing a new stem myself. I was hoping to get some advice on where I could look for a new stem online and any general advice.

This is a stock picture of an '84 Trek 520 that looks like mine.
