Pass the bong please.....

yes to all of those things. You will have to cut down the bolt and nut under the oil pump and drill out the windage tray to accept the studs and make a new hole for the back stud. Went through the same crap. Also if you are using a morroso oil pan and pick up yes a little hammer adjustment is needed to get the pick up to line up in the pan. i just massaged the windage tray a bit and it was fine just make sure it has clearance from the crank but mine wasnt even close.
