I know that MacFab in Toronto, Canada carries both of these (or recently did - if they are out they could order it for you likely). You should call them up, I don't have the number handy but directory assistance could get it for you. They are pretty cool people, and though they aren't really a mail order place, they'd probably ship it down to you.
You should also check
ebay regularly because there are a couple of people who frequently sell shag fur on there.
