AZ missing ac bracket

[mike1971c10]

After seven years I'm going to put the ac parts back on my truck. When I bought the truck the ac parts were on the motor but not hooked up so I pulled them off. Now I see I need 7 brackets to go on my '71 c10 small block. I can only find 6 now. The engine is not original, so I'm not sure what bracket I'm missing. Here is what I have. Is there a bracket that bolts to the intake to adjust the compressor? One is still on the exhaust manifold
