Originally, I had the door latch and striker as part of the same task (i.e. the latch closes around the striker and that's what keeps the door closed). I started working on the doors prior to putting an engine and transaxle in the car. The only way to get the engine and transaxle into the car is to remove the body shell. This is already complicated by the rear hatch hinges and the front hood latches. Both of these have to be disconnected before the body shell can be removed. Installing the striker, adds a needless complication to the removal process. So this part will have to wait until after the engine and transaxle are installed (sometime in 2014).

This is the latch attached to the mounting bracket. Factory Five purchased the latch from a third party. I am pretty sure they machined the mounting bracket.

Likewise the doors have to be removed from the car before the shell can come off. The doors seem less problematic that the hatch hinge and hood latches, because by the time I have to remove the doors - everything related to their fitment should be in place per the arrangement of the hinges on the doors.

The curved part is the cut out area where the latch is exposed as part of the door. 

The latch has a similar arrangement in terms of adjustment as the hinge does. The work area for the latch is very tight, and difficult to work with. The hinge and the latch need to be tightened down together. This happens prior to window placement, since the internal frame needs to be solid so the window tracks can be attached. There are a bunch of pieces here and they all have to work together.

This is the latch mounting bracket connected to the internal frame on the rear side of the door. To the right of the internal frame, the opening for the external door handle is in close proximity to the latch controls. This will be covered up and closed in as I am opting for shaved door handles and internal door poppers.

Placement of the latch is dictated by the formed cut out area for the latch and the depth of the latch inside the door. In other words, enough of the latch needs to be visible so the striker can properly mate with the latch. I already have some issues with the drivers side hood latch and I don't want to repeat that mistake here. Eventually, I am going to have to adjust the hood striker to line up a little better, but I am holding off until the body shell goes back on for good (i.e. after the engine and transaxle are installed).

This photo shows the internal frame connected tot he latched, the rear window track and the  cables going back to the motor, and the internal door popper. The items still missing at this point is the glass, the fixed tracks, the filled in exterior door handle (i.e. shave door handle), and the internal mechanism to open the door from the inside of the car.

I used the Dremel with a cut off wheel to cut the fiber glass and open up a slot for the latch mechanism. The fiber  glass is very thin here as it is on the hinge side. Once I had the latch comfortably exposed, I tested the latch mechanism by pushing the striker into place.
