I big thank you goes out to Dominant Saws. They have sent me one of their Wiseco 372 pistons and a set of hybrid ceramic bearings. I plan to put the piston in my "new" 372. I don't remember if I put ceramic bearings in this saw or not. If not, the bearings will be going in this saw as well. I haven't yet made any measurements, but here are pics of the items.
