On the piano I mentioned above, replacing the dampers was unnecessary. The trichord wedges fit very nicely in the new bichords which were slightly wider since we used the original agraffs. If we had switched agraffs we would have had to switch dampers too, but using the original agraffs eliminated this need. A little hokey? Maybe! But the piano is kinda hokey too so it seemed appropriate! And it saved the client $$.
