I dotn know what "he" )as in the seller on e-bay) meant, but 90-93 is 4th gen and the parts are not interchangeable with anything else.
So saying 93-97 is mixxing generations and saying that the bumper light shown will fit a 4th gen is incorect. (unless there some modification done and I cant see it)
BTW I would love to figure out a way to make the 94 hood and grill fit my 90. Will never happen though
