Accessory brackets

I bought all the engine bracketry off a 75 Blazer with 350 engine to mount the ac compressor and power steering pump. Or so I thought. Apparently I am missing another piece that bolts to the back of the pump. Here are a couple pics of what I have installed. Can any one tell me what’s missing and maybe send me a pic of the piece? I’d much appreciate it.

Re: Accessory brackets

That looks like one sold by the header maker. With stock manifolds I will need a stock bracket. Thank you Tx.
Anyone else have a pic of the stock piece?

Re: Accessory brackets

That one is for non a/c. I am finding there were a half dozen or more different brackets from factory depending on application and yr models.

I believe for the 75-85 year engines I need this bigger bracket for my power steering and a/c setup. This was gone from the engine I got the other brackets from. I am now narrowing down the yr model and image to look for that bracket. I think another visit to the jy is in order now that I have a better idea of what I am looking for.
Thanks for the help.

Boog - you mentioned in your original post you bought the parts from a 1975. I'm not certain what year vehicle you are attempting to install to. Your pictures show a short R4 compressor but the 1975 brackets you purchased would have been for the long log A6 Harrison compressor.

Which one are you attempting to achieve?

I've attached the diagram for an A6 installation and brackets from the GM factory manual. If you need to accommodate a different compressor you need to consult the correct year manual which are available here in PDF form after searching.

That is the style of bracket on my '81 with the r4 compressor ("pancake" compressor in case I got the naming wrong).
