Help Retrofitting 1979 Price Pfister Shower valves/trim

[AndiUpgradesHomes]

Hi All, I have two regular stand-up showers with 1 knob and shower head only, 1 shower over tub with a one knob control on it, and then one shower over tub with triple faucet and tub filler which I need to either retrofit or replace. I know that they are Price Pfister from 1978/79.
I've reached out to Pfister support and since last Thursday they've given me nothing back. Can anybody please tell me what replacement parts I need to make these work? Thank you very much

the head and arm: just get a normal shower arm and any new head you like...there is no retrofit for that PP ball arm.
The cartridge and style is the Avante. look up price pfister Avante.

Awesome. Thank you! I found the 1979 Avante, and a direct replacement for the pull/turn faucets. I tried a 3.4 Glacier Bay standard shower arm to replace the worn gold original and it didn't fit. Are there any specific brands that are universal and will fit in the wall? I think the contractor has thrown away the previous arms...I appreciate your direction and telling me the name and brand of the original trim!!

The shower arm threads are 1/2”. The old arm gets removed and any common shower arm will screw in.

Thank you. Glacier Bay is admittedly poor quality, I'll try a different brand. Please have a wonderful day! I really appreciate your help!

The 3 handle is probably a Verve style stems I believe the stems are 910-374 and diverter is 910-385. Rebuild kit should be S10-230. Probably not gonna find polished brass, just chrome. Reuse existing trim if set on polished brass.
