I'm going to assume that they do not sell the clear cover apart from the headlight housing as it is manufactured as one whole unit. I would try calling around to some local junk yards or pick-a-part locations if you just want a disassembled one.
If you don’t go for junkyard part, you might as well get the clear corners kdm version. If your gonna pay through the nose, might as well get the bad ass look. KDM Led Clear Corner Headlights kia stinger
