At least keep the front brake. Keep the tires, just rotate the front to the back.
You might be happier in the long run by having a dedicated fixed wheel built for you, it's a little more
money out-of-pocket, but a longer-term investment than than a bum-bike set up.
I converted an '83 Moto Mirage this way for a friend, and it worked out just fine.
I'm considering buying a flip-flop or fixed hub wheelset instead of rigging the rear wheel. I think harris cyclery has 27" wheelsets for relatively cheap. Maybe I can get a LBS to build a set for a reasonable price. I think I need to replace the brakes (or at least pads) for sure. They're scary. If I have aluminum wheelset built, would I need to replace the brakes in total? (Old weinmann brakes).
