Ruud heat pump capacitor size

Question

Hi, I am currently working on a five ton Ruud heat pump. The run capacitor for the compressor is bad and all the information is rubbed off of the capacitor. Can you tell me how to get the correct size capacitor. everyone i talk to at the parts stores just tell me to use a hard start or the turbo 2000 but can not tell me the correct size. The condensor model number is upca-048jas and the compressor model number is elcrml 0400
