Well I can give you three tries. Look in your local phone book for taxidermy shops and call them and explain what your looking for you'd be surprised at what they have for trim pieces.
Second try Moscow Hide and fur
http://www.hideandfur.com/ if you don't find what you're looking for on the site call them and tell them what you're looking for.
Third you can try Coffin Creek Furs
http://www.flytyingfurs.com/ I don't see it on the site but you can call and ask.
Other than that check out some of the bulletin boards and ask on them if anyone has some.
Hope this helps.
