Small block alternator bracket

Hi all,

I have a 72 Duster. No frills 273, aluminum water pump.

I am looking for an alternator bracket (triangle) that is mounted to the water pump. Also looking for the water pump pulley to go with it. Single groove as I have no A/C.
Trying to work through all the garbage the previous owner cobbled together.

please let me know.
Thanks,
Chris.
If you don't find what you need, if you can post a picture of the piece(s), I might be able to help. Just went through my storage truck, and found a lot of brackets. Most I don't know what they fit.
PS: Picture can be from anywhere. Doesn't have to be your vehicle. Just need to match up what I have.
