You seem to need a 1" threaded fork for cantilever brakes. but I have no idea which length steerer you need. Also you need to make sure the fork is suspension corrected or whatever the correct term is, otherwise the geomentry of ypour bike will be slightly off.

So I just need to measure the steerer length. To my knowledge the tube needs to be cut to length anyways. As long as it's long enough.
