These replacement weather seals are designed specifically for 1978, 1979, and 1980 Oldsmobile Cutlass 2-door coupe models with a standard solid roof. Compatible vehicles include the Oldsmobile Cutlass and Cutlass Salon coupes from these model years.

No. These weather seals are intended for 1978–1980 Oldsmobile Cutlass 2-door coupes with a standard roof only. Models equipped with factory T-Top panels require specialized weatherstripping designed specifically for the removable roof configuration, which uses different sealing paths and components. Please see our related product page for T-Top models.

(4) Are these weather seals manufactured to match original factory specifications?

Yes. Replacement weatherstripping for the 1978–1980 Oldsmobile Cutlass 2-door coupe is manufactured using modern production methods such as CAD design and CNC machining. This process allows the seals to replicate original factory profiles and maintain an OEM-style appearance and proper fit.
(5) What materials are used in the weather seals for the 1978–1980 Cutlass coupe?

These replacement weather seals are typically produced using high-quality rubber with micro-closed-cell construction, allowing the seal to compress evenly when doors or trunks close.
