I did a search on SB and found these photos on another site. See the next post for the remainder of the photos.
-3/16 hole drilled in lower left corner of lock plate to install the locking tab actuated by the key. Latch assembly is installed and a foot long 3/16 aircraft drill is used to drill through the inside panel, pass through the hole drilled in the latch plate and through the outside door skin; this aligns everything. Assembly is then removed from door.
-Locking tab is brazed to a 10-32 slot head screw and slot is made wider for flattened shaft from key lock to seat into.
-Door handle is turned down to make sure latch releases.
-Lock tab (white) is raised to the up (locked) position with key; this prevents the release latch arm (orange) from moving enough to lift out of the notches which releases the part of the door latch one can see from the outside.
-The end of the lock shaft has been ground flat and the notch filed in the locking lever shaft so it's a snug fit. The 3/8 steel tubing captures the lock shaft so it can't slip out.
