I have the wrong bracket. I have one that is fixed and not adjustable on the bottom. I will dig through my bin of crap tomorrow and see if I have one. I discovered I only have one groove on my PS pump and my water pump. I guess I will route crank-ps pump and crank-water-alt. IS the second groove on the alt for a/c or air pump?

I'm answering just so you know people are interested but I don't have the info you want. My Bronco 302 only has 2 belts: one drives the alternator and water pump, the other drives the a/c compressor. The a/c belt is tensioned with an adjusable idler pully. The way the grooves line up should tell you something. I've seen Ford trucks with 2 belts driving the water pump and alternator but in your case the second groove might well be for the air pump. Keep digging, you'll figure it all out.
