Erin, the white lever in the pictures is the one you fabricate and is turned to locked or unlocked by the key. As you can see, the white lever when in the locked position prevents the pawl arm (orange) from moving up out of the notches in the cam. The critical part of the installation after the latch is modified to lock is finding the exact spot to place the key cylinder so it's exactly in line with the pivot in the lock lever. I use a long 1/8" aircraft drill (called a bit by non machinists) to drill through the inner door skin, pass through the pivot hole for the temporarily removed locking lever, and finally through the outer door skin. This aligns everything. If the door is already painted inside and out then use a #8 clutch head screw to fill the hole you drilled in the inner door skin and people will think it belongs there, especially if you put a second one in the same place on the other side.
Denny, yes we do a lot of rods but also many back to original. If you want to look at a 53 AD that has been in seven shows and taken seven first place awards for originality then go to page eleven, pictures 172-175. There is no splash guard between the front bumper and grill in these pictures and bias ply tires are installed for just the shows. It loses a couple points for the turn signals and right tail light but so far has outpointed others. It is not a trailer queen but driven in downtown Dallas on many occasions.
