We get this question ALL THE TIME. For the benefit of other budding DIY folks, I will be a little bit brusque with this answer....nothing personal, because you just didn't know and we all have to learn:
Would you go to the Ford dealer to buy a new fender panel for your Toyota! Shower parts are often not interchangeble among different models of the SAME BRAND! They are NEVER interchangeable between brands.
You have a very common 3 handle shower, so there is some variety of replacement trim available. You can find an assortment of knob and lever style handles, and will be able to find chrome, brushed nickel, and venetian bronze finishes. ALL will be made by Price Pfister, or will be aftermarkets marked FOR PRICE PFISTER.
