ABX has the STC and most of the ABX 767s still flying have these, along with all ATI 767s (except for N712AX). American also has some throughout their 757/767 fleet but I heard they might be ripped out very soon.
A lot of the older ABX 767s were just parked at ILN for a long while and these airplanes just have the EADI/EHSI set-up; I think N702AX (N650GT) was one of them.
