IMO, if you have too much end float (without packing) you either have a
heavily worn distributor drive gear bush (in the block) or the bottom of
the distributor pedestal which bears against the side of the gear is worn.
I have always had to add some "packing" under the pedestal to get end
float.  BTW, I never found the instructions in the manual a very accurate
way to determine end float.
