Guess you should have looked at the Internet.
Any decent plumbing supply should be able to order it. If not, and I don't recommend this because it may arrive broken, but, Home Depot sells it online:

All they do is ship it to the store by common carrier, unlike the way it comes on a pallet to your plumbing supply place, so you really need to stand there with the HD folks and open the box and inspect it with a magnifying glass, then drive it home. It's easier to just ship it to your job site, but have fun returning it if it arrives broken. If you ship to store, you can reject it right there and HD people are the witnesses.
Also, Zurn Z5792. I think that one comes with a flush valve.

I'm also pretty sure that installing it isn't a DIY job.
