FYI, the DB Electronics alternators are available with your choice of pulley at no charge. I bought my first 170 amp model from them. For my nicer truck this time I got the black powder coated version. They evidently can/will charge the same amount for either the 170 or 200 amp internals. I was adamant about getting one with black powder coat, and the guy I talked with this time wasn't very smart. After asking my questions and telling him that I was a previous customer, he insisted that I pay the higher price for a non listed part(not on eBay). I wanted the cheaper price that shows $200 for the OHV(200amp), plus $29 for powder coating.
I ended up getting mad at him and asking for the boss. It turns out that he was the brother of, and at least the brother respected my being a past customer. He gave me the $229 price(w/overdrive pulley), they had it in stock or buildable the same day. I received it two days later. They are very good, but like any business there are odd balls working there. Regards,
