OK- A LeTour is still from the freewheel era. If the rear wheel's shot, then replace it, and throw on a single freewheel. As far as I know, a 27" rim on a fixed-gear hub would be a custom build. That means $$$. A replacement rear wheel should be about $25 if you stay with a steel rim, $35 if you go to an aluminum rim.
FWIW: I have a LeTour from the Mississippi Schwinn era:
