On a Ford, it is the bearing pad in the block that locates the distributor gear for correct mesh. But you have to install the gear on the distributor to the correct tolerances given by Ford, so that the gear actually contacts the pad in the block.
If you set the gear too deep on the distributor shaft, then the downward thrust of the gear is absorbed by the small bearing in the distributor. This will shorten life of distributor. Also gear mesh will not be correct.
If you set the gear too shallow on the distributor shaft, then when the distributor housing is tighten via the clamp, this will jam the gear hard into the pad in the block and severe wear will result in short order.

On a msd dizzy, you can adjust the collar, that sits on top of block and set to recommendations. Then check the pattern that is what I was talking about.
