Whirlpool went to a short centerpost, don't recall when. There's a NIB belt-drive baseplate left at the long-closed Whirlpool dealer's shop in my home town. Not sure if it's standard capacity, 18#er, long or short centerpost. A member expressed interest but I can't get Ted to state a price. He wants to get at least the original dealer cost, but he threw out the price books. I can try again, I suppose.
