Source for Alternator Rebuild Kit

I am looking for a place to get a rebuild/ upgrade kit. I had tried this place:
http://store.alternatorparts.com/ho7005-chrysler-square-back-alternator-80-amp-upgrade-kit-1.aspx
but after 11 days not hearing from them/ receiving anything, I gave up on them.

Has anyone found some other place? They aren't difficult to rebuild, so I would rather rebuild my own than by a new one.
