I appreciate the offer and I might take you up on it, but for now I've decided not to use this distributor. The lower shaft collar is plastic. So, when I got it, the axial play may have been in spec, but I don't trust it in my crank case any longer. Looks like a few of the cheaper distributors use plastic. I've also been looking the housing over and it looks pretty beat up with a few chunks missing here and there. I think someone used this one as a hammer before turning it in as a core.

I will still do all the checks you guys have recommended, but I would just feel better starting over with a new housing and one that uses a metal collar. The Spectra would probably do the job, but considering the MP. I see if you search right and hold your tongue just right you can find one on Summit for $117. I'm going to assume it's a better starting point than the Spectra or reman one I have.
