I have two bags; one bag has two pieces and the other has one piece. Selling as a complete 'lot' of three pieces in two bags, still in original Sony packaging. I am guessing these are head shims, as they appear to be non-magnetic brass, but your service diagram will show exactly what it is and where it goes.

There are exactly zero of these available elsewhere on the web right now, so if you need this, better grab it before the next guy does!

Ask any questions, but since there are no others out there to research, I'm afraid I don't have much else to share about this part. Your original service diagram should list this part number if you need it.

NOTE: I will stuff these in an envelope with a stamp, and shipping is $1.00 (domestic). Risk seems very low they will be damaged.
