Replace windlass on Nonsuch 36 with what new windlass

Intuition IX. N36 in Freeport, The Bahamas. She has a Lewmar that is likely original equipment. It has a vertical drive with a large capstain. I know the chain size. The gear seems broken. The yard can not locate the gear numbers im the ancor locker. Does anyone know the model number? There is some confusion because it seems Simpson Lawrence too over Lewmar. I am trying to replace windlasses so I can use the same hole in the deck
