Has anyone rebuilt one?

I would like to try to rebuild mine so I have been on the interwebbs looking for parts.  Is it necessary to replace the rectifier?  I feel like I should because I am in there anyway?  Right?

Anyway, I have found parts on Larry B's but their recitifier is out of stock and it is $40 more than other places I have found.  This is what I am looking at, any thoughts?

Pretty straight forward to rebuild an alternator. As long as the case is good and the bearing spots in the case are good I would go for it. My last alternator I want to do that but the rear half of the case was fried and wasn't holding the bearing properly. I was stuck buying another reman'ed.

I like the price on the diodes and parts...

I wonder if Nation's Alternators would sell you one of their high amperage diodes? That would surely give you some buffer room. Not to mention I think they are mounted on copper plate to dump heat better.
