Hey Fred, thanks for the info. Either the truck I stripped was missing part of the PS bracket, (I don't think so,) or I lost it, (possible, but I went back and looked, nobody had touched anything,) or who knows. I have seen pictures of what you describe, but the alt bracket bolts to the water pump and to a boss on the intake about 1 1/2" in front of the thermostat housing. There is one threaded hole in the right head where the ground cable is bolted, and three in the left head in a triangle.
What I have seen matches what you describe but not what I have. Thanks for the input, but nobody at the local speed shop recognizes what I have either.
best wishes,
Les
