FWIW: the stock Varsity's stem clamp is 1" (25.4mm) I.D., not the more-common-now 26.0mm or 31.8mm. That means you can substitute an old/cheap standard mountain bike handlebar without changing the stem.
I did a couple handlebar conversions on Schwinn bikes way back when. It was kind of fun when many different handlebar were easily interchangeable.
