I just did mine. The photos aren't much help other than orienting yourself. The install is best done with the fenders and wheelwells in place and the car on a lift so you can install parts, drill and proceed without killing your back.
You need to install the door without bellcrank, instead drop in a 1/2" bolt 1 1/2" long to locate the crank hole for the wheelwell. Drill this 1 1/4"...yes it is that big if you want to get the crank through the hole. This hole should be overlapping the slanted part of the wheelwells by about 1/4" so use a holesaw with a 2" arbor to guide your cut.
Then install the crank. Attach the front pivot support to the crank and locate the 2 bolt holes attaching it to the very front of the wheelwell. This pivot bracket should be at about a 45 degree angle to the leading edge of the wheelwells and not cover the 1/2" hole that is there already.
Then preassemble the actuator can plus the rear cross support. Attach this to the crank and with a buddy holding it steady, mark the 3 holes for the rear cross brace. NB; the outside edge of the brace must be clear the of the inner edge of the fender extension. It is a good idea to check the fit of the plastic shrouds at this time to be sure you have the brace in the correct place vertically at this time.
One other hint, when mocking this up use the bushings and wavvy washers to get the slop out of the linkage. And don't forget to drill 2 holes for the RS turn signal wires that go through the wheelwells back of the linkage.
