New in original packaging 3.5" removable media drive mounting kit for a Mac Quadra 800 or 840, or a PowerMac 8100, 8500, or 9500 (won't work with a PowerMac 8600 or 9600). Kit included mounting sled and adapter bracket, stub SCSI cable, faceplate with 3.5" removable media (Zip, Jazz, 4 mm tape) opening, installation instructions, and bonus closed facepiece from one of the above computers (like most older Mac equipment the closed facepiece is yellowing). $17 including shipping within the continental US; other locations contact me and we'll work out actual shipping costs.
This was a "floater" which got separated from the boxes of (now vintage) Mac equipment I accumulated; coming soon a virtual garage sale of all sorts of Mac goodies.
