^ I'm in the same boat as Nate; I don't ride enough though.
Nate: sorry about the crash, glad your damage to you was minimal.
A trick you can use on the derailleur hanger is to pull the skewer of a rear wheel, remove the derailleur, and screw the wheel into the hanger (should be the same M10x1 thread on a rear axle, at least vintage is). The wheel will help you gauge whether the dropout is aligned with the actual rear wheel in the bike.
