P/N 17779 is the correct part im looking for.  That p/n is in the NPD catalogue but they told me that if there is no price attached to the p/n, it is because they don't have it.....its just here for reference.  P/N 17779 is what I need.  Thanks.  I called CASCO, they said they would get back to me but never did.  Thanks

B5S 17779-A is the complete PN for a 55/56 BIRD. It may help with the search.

Good Luck with it!
