Ok so there is no keyway in this?????? So which way des it go on? I see a mark on it but where does it point. Thanks in advance-Joe

 

Set the number 1 cylinder at top dead center. Install the hub with the little cast in arrow in the 12 oclock position. More performance sells a keyed hub for about 75 ( I think) or maybe they will key yours for 75. I forget!

 

thank you very much
