(2) Do these weather seals fit both 2-door and 4-door Pontiac LeMans models?
No, these weather seals are designed exclusively for 2-door coupe configurations. Fitment differs significantly between 2-door and 4-door models due to variations in door length, roofline geometry, and sealing surfaces. Installing coupe-specific seals on a 4-door LeMans will result in improper alignment and sealing.

(5) Why should I replace the weatherstripping on my 1978–1981 Pontiac LeMans?
Over time, original rubber weatherstripping on classic vehicles can dry out, crack, or lose elasticity. Replacing worn seals on a 1978–1981 Pontiac LeMans 2-door coupe helps restore proper door, window and trunk sealing, improve cabin comfort, and prevent water leaks or wind noise while maintaining the original fit and function designed for these specific Pontiac A-body models.
