The body is a 31 and the doors do overlap. (in fact, I believe that all model A sedan doors overlap) I decided on a different approach than the tapered shim. Since the striker bolt has a threaded shank and screws in from the outside of the jamb (nut plate is caged on inside of jamb), I took my trusty air grinder with 3" cut-off wheel and ground a reverse taper on the striker bolt, so that the outside diameter of the striker bolt now sets 90 degrees to the face of the latch in the door. I seem to be having some suuess with this approach, and if I do totally screw up the striker bolt, it can be unscrewed and replaced without messing with the paint on the door and the jamb. Its raining outside right now, so I have to wait for the rain to quit and the roads dry up before I go for a test drive and see what happens.
