Weird set up need new valve, Help!

[Scomf8]

My shower has a weird set up I have two heads, one temp control valve and two handle controls that turn on each shower head. The temp valve is corroded and I need to replace but want to leave everything the same. I have attached a pic of the valve. Can anyone recommend a replacement valve or do you you know if I can replace with a delta Faucet R10000-UNBXHF MultiChoice Universal Shower Valve Body for Shower Faucet Trim Kits. Please let me know your thoughts.

Thanks

The Delta is a much used valve and easy to get parts for.

This looks to be California faucet. These are still in production and they have many trim sets. Other mfg's that use this valve is Watermark Designs, Cifial, Mico Designs, Moen. This is a quality system.
