Does anybody know if the G56 has the same size input shaft as a nv5600? Or atleast the pilot bearing size. I have a brand new flywheel with southbends heavy duty ball bearing pilot bearing and am wondering if I can just do a new clutch disk or if Everything has to be changed. I know that the G56 comes with a dual mass but I have read that it can be replaced with a single mass, just not sure if the single mass replacement is the same as the flywheel I have now? I would just cal Peter but they aren't open till monday...... Thanx Lowell
