well i finally got my 235 back from the machine shop. after five months of waiting, and locating different parts. so im putting the motor together and sure enough,as precise as i try to be, i cannot find tne bolt that holds on vthe oil pump. i believe it was a specialv bolt with a lock nut on it, and a tapered vend to go into the pump shaft. does anyone knoe where i can get one? any help would be great. thanks
