The clutch pulley appears to line up with a second groove on the water pump. I don't have a second groove on my water pump though. I need to put it back so I can take some pictures and get some better ideas as to whats going on.
The bracket and compressor you have would be off a power steering car and it would have an adjuster pully. You can see the adjustment slot in the picture in bracket you have. It wouldn't matter if it isn't needed for your application. I have to be up in just over 5 hours so I am going to bed now. TTYL.
