Looks like 359937 was the service pan, discontinued/superseded to the 252 pan?.
Not that they're available either but the original '61 part # appears to be 3769761 and the '62 part # 3789629...earlier #'s?
Did you see this used one on eBay @ 399 BIN?
Need repair and pics are poor but looks like the correct vertical ribs, does the inside pic show two ribs one one side?
