It depends on how close of a replica you want to create. You could go with a nice set of original or repro Ceriani forks which would give you mounts for a good selection of proven performance calipers. You could also look at something like GL1000 forks. I want with a set of Betor forks, very similar to Ceriani, arguably similar performance but without the price and added a pair of Lockheed calipers. Looks period, should stop a ton better.
