Have a 1969 FLH flatside. It has no oil seal slinger. there are no threads on the case as in earlier model generator bottom ends. Was told it is a transition year for motors and did not have a screw in seal.Cannot seem to find what seal goes there. I was told that the threads were torn out but then some one else told me about the Harley transition year for these cases. HELP, any and all will be greatly appreciated.Part### ? Thanks,
EDD
