The EPC shows the SW20 A/C Comp. as part number 88320 - 17090, later superceded by 88320 - 17091.
Bad news is that no other model on the EPC shares that A/C comp.
If I were you I would quote those numbers to the Part Dept at your local Toyota dealer and see what they can tell you.
If they are useless then call NipponDenso Aust, ask for the tech. department and go from there.
