The sunroof seal glass for the 92-99 is one piece, and is NOT something you'd buy the glass for. GMPD shows them as one piece which doesn't make sense.
Edit. Found yet another weak point with GMPD. RockAuto didn't have it either.
If you search in BODY parts for your car, then select roof, then sunroof, it'* listed as 'weatherstrip', item 6 in th illustration.
You'll have to ask them for the price. Since GMPD wants 50-something for the glass AND weatherstrip (it might be no glass, not sure), this can't be much.
