Beginning January, 1987, a new style side roof rail weatherstrip is used on 1987 Regals without Hatch Roof Option. These new weatherstrips exhibit very little appearance change, however, they are thicker and softer to minimize wind noise.
The new weatherstrips are available from GMSPO under part numbers:

20737659 - Left Side
These part numbers supersede current part numbers and apply to 1978 thru 1987 model years.
