I would verify that the existing wheels are 700c. The early 80's Trek 720's were, I believe, spec'ed with 27" wheels. If it uses caliper brakes (which I have seen on some 728's), then it could be no problem. If his 720 has cantilevers, a conversion from 27" to 700c is possible but can make brake choice an issue.
Might be worth verifying what is on there now. I do have some very nice, well built 36h, 126mm 700c wheels if you want more specifics.
