I needed like 5 of them about a year ago.... 5 out of 7 machines I bought in 1 lot were missing them. luckily I stumbled across a good deal on ebay for something that looked close, but I didn't have the PN. Think it was 10 pcs. for under $20, so I bought them and was thrilled that they happened to be correct! I was figuring that if the caps didn't fit I could just swap out the whole thing. Luckily they happened to be the right ones. Makes me think there will eventually be someone else that might need one....
