Thank you for your inquiry! Yes, the Delta Classic 17 Series Trim T17430-SS will work on your older 1700 series valve and cartridge assembly, As long as the screw holes on your large round escutcheon plate are at the 1 and 7 o'clock positions and you do not have a push button shower diverter directly below the off and on handle. Any of the Delta tub and shower trim kits that start with a T17, except for the T17T series trim kits will interchange for you. The cartridges that come with the new trim kits will not fit your valve body, so you will need to reuse your existing cartridge (RP32104 White cap).
