Whew, I thought I was the only one who bent that rod:p
Solution of course, is to loosen the pivot bolt, etc.
There were two designs of alt brackets, one with a toothed bracket and special bolt, and the familiar infinitely adjustable, funny looking adjuster nut thingy. You can go to a yard and grab whichever alternator you want, with either bracket, and the alternators are the same.
If you can find a small rebuilder like the one in my town,( San Jose Generator- on San Jose Ave.) you are in luck as these people are great! They will put in new bearings, rewind the armature, or whatever. Like new.
Just forget Kragens!!!!

They guarentee them for life, but you have to keep changing them out every 6 months!!!
