Wow, this is interesting...
I was just browsing through my AllData section on the '88 Cherokee. There is a rather detailed discussion on how the "self-aligning" Distributor mounting tab apparently doesn't self align very well. The document explicitly describes a process of cutting off the end of the Distributor Locating Tab that usually "hugs" the ditributor hold down bolt. The idea is to allow manual rotation of the distributor for timing types of operations. It then also describes a process by which you would "statically tune" the distributor by taking a sacrificial distributor cap and cutting a hole or window in it around the #1 spark plug post. You then manual crank the engine so that the timing mark on the dampner is at 0* top dead center and the distributor rotor is suppose to be at .020" past the #1 spark plug post. Hey, why doesn't anyone make a clear distributor cap anyway?
This is critical information for anyone who is replacing a distributor. I guess you can't depend on the locating tab to do the job for you. This might explain my recent rash of sporadic misfires that have been plauging me.
Though you all might want to know.
