I am overhauling a bike with a Campagnolo bottom bracket, and it had (part of) the plastic sleeve that is supposed to keep out dirt and grime. From what I can tell, it is missing the second smaller part (and the piece I have has a large crack). I saw a few on eBay for sale, but they seem quite pricey for a tiny bit of plastic. So a couple of questions:

1) Does anyone have measurments of that second smaller piece (2110/1) so that I can try to make my own?
2) Or does any generic bottom bracket sleeve work (even the accordion style ones)? If so, where can I get one that doesn't charge a ton for shipping? I saw these: but shipping and min order is a little high.
