No such thing as being a tooth off on a mopar..
the intermediate shaft drops in and has a slot.
you can move the intermediate shaft to where ever you want the distributor no. 1 to point to as long as the rotor is pointed to 1 on the cap...
now if your distributor body is giving you a problem as far as the vacuum advance hitting something...move the intermediate shaft and realign the distributor..
get a large screw driver and turn the slot clockwise the gear will go up the cam gear...then move it....it might that a couple of tries since the gear will slide down the cam gear and not point to where you want it to
