It looks like the AC-44 is the one that's discontinued. There are a bunch of AC-44xxx available but the suffixes indicate that they're extended reach or whatever. They're not the original spec AC-44.

The AC-45 appears to be available. Rock Auto has them on sale for $.50 off right now at ~$1.30 each.
