t3 compressor identification help

mine is on the right. the numbers on the compressor were grinded off for some reason. all i know is the compressor wheel has a 46mm inducer/60mm exducer (58.7trim?). with my measurements, the AR for it is .36 which doesnt seem right. what does it look like to you?

the turbine housing is labeled with a .63AR. on the turbine wheel i measured a 48mm inducer/58mm exducer. how do you calculate the trim for that? i get a whole number if i do (exducer^2)/(inducer^2) and 68 trim if i inverse it.
