well the easiest way is to throw a few balls (with a low flairing ball, preferably plastic, but symetrical at very least) and then get to a spinner when you can see the track.. Mark the Inside (closest to fingers) track line and go All the way around the ball, put it on the spinner until you get the line balanced (it spins strait around, no wobble, like a lattitude line on a globe) once you have that, the top of the ball is your PAP, mark it out and measure from the center line of your grip, over and up or down. That is if you can get to a spinner or you have a way to mark the oil line until you can.
You can also estimate it by setting be ball on a ball cup (or cup holders work) and try to measure out the line from line down to the table, do it at 4 sides until its equal and you will be real close. Mark the top of the ball and away you go to try it out.
Other wise, you can fiddle with it a bit by taking some tape and following a similar procedure with the oil lines and estimating where the pap will be, then marking it with tape. Then throw the ball and see if you the tape stays stationary going down the lane. If not, move it around until you find that spot where it is. Then you can know where it is, and you could reference your drilling from there OR bring it back here and we might be able to help you some more.
