I’m about to ask a stupid question lol. I ordered an oil pump with filter dished cam (PN 115160L). How do I install this thing, lol? The new pump has a bolt thru it with a nut on the back side while my engine has studs for the pump. Do I remove the bolt and nut from the new pump and install like a regular pump on the studs? If that’s the case I’m guessing the bolt/nut combo was for shipping purposing only? Thanks for your help and for great products, I’m a big fan.
