Scott Carlson, could not find a lot on this one. Try the links below, maybe make an inquiry at the second link to see if they can cross reference your device or give you a part # for replacement screen. Do leave question open if links fail to produce and other ifixit volunteers may have better solution. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.
