Camaro L4-151 2.5L (1982)
1991 "F" style vehicles built after the following VIN breakpoints will use new T-Top roof opening and panel weatherstrips.
ML186669
These new weatherstrips have a drain system added to the butt joint contact areas on the opening portion of the weatherstrip, and use a new butt joint
angle at the contact areas, see Figure 1.
The new panel weatherstrip also mounts in a new retainer. The new retainer is slightly longer than previous styles and has slots in the outboard surfaces
to better retain the tabs on the outer ends of the weatherstrip.
