I have a 1985 Schwinn Le Tour Luxe. I have replaced the bars, stem, levers and rear derailluer. The 27" wheelset needs replacing. It wears new gatorskins.

If I convert to 700c, I'll have to replace the original dia compe canti brakes with something that has some adjustment room.

If this was your dilemma, would you buy 27" or 700c wheels for the bike?
