Ignition lock cylinder email address on 1998 Plymouth Voyager

I have a 1998 Plymouth grand voyager with an ignition lock cylinder that needs replacing. Apparently it has an unusual type of lock cylinder set up according to the dodge dealer. The lock cylinder does not have the typical hole for the retaining tab release in the diagram shown by Plymouth. Was there a change in the cylinder design that was not be annotated? The large round lock cylinder is made of mild steel, not like the lock assembly which is made from pewter if this helps. I used alldata, but this did not show the design I have.
