Exactly, Mark. Use a hole finder to locate the ones in the fuselage sides.
This method helps match the cabin curvature exactly as the door halves cure up. Trimming later will let the door settle into the hole like a tapered cork, so remember that some possible shift can occur if all the subsequent iterative door trimming is done on the same 3 sides of the door vs all four. The tendency will be to allow the door to dangle in the doorway (on straps of aluminum held on with cleco's the way I did it) and trim ever more off the bottom and sides till drops into the doorway perfectly - except now it's lower in the doorway than you intended.
>> Trim the top edge, too, as you go - keep it centered! <<
Happily, I discovered this drift before it became too much and I lost too much of the bottom door lip. That would not have been good.
