As the recent Accessories thread on the cush drive links here -
FYIW, Triumph P/N for the Tbird Sport cush drive is T2012211. Got it from Hermy's. Put it in my 05 Speedmaster last October. Before that I tried to salvage the old one by adding pieces of rubber cut from an old inner tube, but was never able to get it tight enough and still get the hub back together. The Sport cush fit much easier that I was prepared for, snug but no rubber mallet needed.
