Some of the aftermarket replacement castings are a little odd in places. Probably a copy of the casting for a different application that they think is "close enough" to work on a tractor. So far, I have not run into any differences that affect normal setup and tuning, other than replacement points being wrong. One distributor I have did need the screws under the top plate to be ground off nearly flush to keep them from being whacked by the advance assembly. Another solution for that would have been to put a thrust washer on top of the advance assembly and/or shove the top bushing down a touch.
