there is a number on the side of the reed block"boyseen" and then you can call boyseen and they can tell you what part number you need...i did this couple years ago and orderd the reeds from parts unlimited as they are a boyseen dealer but they
didnt list the gg part as a stocked item but put in a special req for the part num and bam i got them but i dont know the honda cross refrence but i think there is one..
