help identifying old Pegasus shower trim - or - tell me what cartridge and valve rough in I need

[johannapanek]

I bought a used shower trim, i know its a Pegasus but there is no other identification on it. I am building a new house so if you could tell me what i would need to buy to make this trim work? I dont know what i am doing.. I think i need a cartridge and a valve? Anything else? and what kinds?

I don't think so because the tub filler has more details on it in the photo and also the rim is inverted instead of pushed out. Thank you though, it was close
