. does anyone know where i can order this part ? does anyone know for sure if the qb78 valve pin will work well in a crosman 160 ? i have a japanese taiyo bobcat co2 rifle that is supposed to be a clone of the crosman 160. it leaks down thru the bore which indicates it needs a new valve stem . i have taken it apart , but mac1 rebuild parts are too hard for me to rebuild that valve pin with his 160 kit - it has to be just perfectly rebuilt. i ended up with a brand new beeman qb78 that i was gonna raid the parts from - but that chinese p.o.s. actually ended up shooting pretty good. i'm dying to find out if this legendary japanese steel is evident with their barrels, and the little bobcat has a good trigger too. - raneman .
