Moen, Unknown shower brand...

[jackieonly43]

No make or model... its a single handle. I already removed handle and was able to unscrew the back plate, but don't know what to do next. I tried pulling it, but without more knowledge I didn't want to force it. Any ideas what to do next?

Moen, either the standard Moen that takes a 1225 cartridge, or the Posi-Temp that takes the 1222 cartridge.
The recent handles have the backing made of plastic.
