It’s like Bill says, sometimes it is cheaper to buy the whole engine (usually one that doesn’t work), than to buy one of these starters. Most of the individual pieces are available at ME.com, I’ve seen used cups on ebay. But, it is pricier buying the individual pieces. I will let you know if I see one or pieces you might use. Keep an eye on ebay, sometimes they pop up for a reasonable price. Like I say, sellers seem to think these things are worth their weight in gold….
