Depends. Most dual pivots will work fine with the lever pull you had in 1960. Then Shimano started dicking about a few years ago (DA 7900 and then migrating down to Ultegra and 105 etc. next time those groups changed) and changed the cable travel by about 10%. Some people don't notice the difference, some people like using the wrong combination (in both directions), and some snowflakes think you have to throw out all your old things and buy properly matched sets of new stuff.

TL;DR - maybe, but probably not.
