Mounting location for door mirror

[Kurbycar32]

i purchased my early 260z with a missing mirror.  On closer inspection I found that my mirror was ripped out of the door, 4 times..  I was presented with essentially a 5" long series of holes in my door so prior to painting I welded them shut with an additional piece of sheet metal inside the door as a reinforcement.  I used a light coat of body filler to smooth things out over the new metal and the door looks normal after paint.  I bought an OEM mirror from courtesy Nissan and now i need to drill holes into my repaired door.  I would like to know the exact mounting location to keep things stock.  My car is an early 260z and I am unsure if that makes any difference.  Thank you in advance
