Need help identifying a cartridge.

[daphotoguy]

This is for a single handled shower in my friends house. His kid broke the handle off so I need to replace the cartridge. Can't find a make/model marking anywhere on the shower hardware. It does have the letters 09.20.99.4I on it. Here are some pictures. Where can I find a replacement at?

My first guess would be American Standard, but I will check later to see if I can identify it at a supplier.

I also though it looked like an American Standard. But every American Standard design I can find uses three seperate round holes in the back with their own individual seals instead of a one piece seal like this one has.

Can you post a pic of the handle and trim plate?

I will post other pictures tonight.

It is an EZ-FLO EZ7010 or EZ7008. Now if I can only figure out where to buy one at. B^) Thanks everyone for their help.
