Ordered this alternator from Rock Auto. It should be a 55amp with an internal regulator at 2:00. However, what I received (pictured on the left below) doesn't seem to have an internal regulator, at least not in the way I'm used to seeing them. The part number listed on the alternator is what I ordered, but before I submit the issue with RA, I just want to make sure I'm not missing something here.
