Where does this part go?

I’ve assembled and disassembled the front of this engine many times but usually it was all done in the same day. Two years ago I took the power steering pump off to pull the engine and now I can’t recall where this sleeve goes. If I put it between the bracket and water pump housing then the pump is crooked. I don’t recall it being between the head of the bolt and the bracket but I could be mistaken. Any help is appreciated.

looks like a aftermarket metal oil pump drive coller for a sbc to me...
