If we're talking about 2 headlight versions, aren't there just three or maybe four different ones?
Up until '82 they looked like your '81's original grille...
'83-'91 had the thick bar across the middle...
and '92-'96 look like what you and I have now...
I don't know what else fits ours, as when I was interested in changing mine, the others were harder to get than just replacing mine with a stock part.
I ended up just painting mine.
