Correct Water Pump for Early 273 w/ AC

I know this is an old thread and you may be past this point. I recently started again on a project I started some 30 years ago.:banghead:I have a '64 Valiant that I am trying to put back together, that I am adding air to also. If I recall, the donor car was a '65 Valiant that I got all the air parts off of. Anyway, you were questioning your brackets, and they are different. Here's a couple of photos, not great but should help.
