hi here are some part #'s for the:
DW-5600-E face protector #74299032
DW-5600-E endpieces(strap adapters) #74243710
these #'s can be used when ordering from any "authorized" u.s. Casio parts retailer i.e. Pacparts, EAI, American crystal works etc. although i just found out that EAI dosnt deal in casio anymore?!
these #'s have been verified as of 4/1/8 and i used both of them when placing an order. i hope this will help some folks
