if your trying to make the bike fit, don't get hung up on a fancy stem to match. buy something that is reasonably priced and fits, then wrap the DA stem in a towel and same it for when and if you sell this great looking trek.
If I may suggest this, stop going to your LBS for simple brake adjustments. there must be dozens of C&V guys and gals near you and perhaps you can get a lesson for the price of a sixer of Ale.
beautiful bike but (yes I am being snarky) why the Craigslist pic? LOL
how about a nice pic of the drive side?
if the tape is for the brake caliper it may be a tad high
a DA seat post too? somebody loved this baby
