10 inch drums are back in stock

Post #14 refers to the "snow lip", though it also helps keep rain splash out. For years, I have seen drums only 1. Original was probably 2 lips. You also see some w/ fins for better cooling (and structure?). My 65 had a spring on the outside, which might have helped cooling, though some say it was for sound dampening. People here have cut the snow lip off front drums so they fit the rear, as apparently did an ebay sellers asking ~$275/drum. But, no need for that anymore since the markets responded (after >5 yr deficit).

Interesting that the drums are stamped "China". Most Centric drums I have bought said "Canada".
