Hood to Cowl Weatherstrip

This two-piece Hood to Cowl weatherstrip is made from original patterns to ensure a perfect fit and effective seal at the rear of the engine bay. It replaces factory parts #4125426 and #4125427, helping keep out dust, moisture, and debris to protect your engine compartment.

Installation is straightforward: these strips mount directly to the body at the cowl, requiring basic hand tools and some patience to align properly. Over time, the factory seals degrade, so upgrading with these will restore that tight fit and help maintain your classic Buick’s value.

• Replaces factory part numbers 4125426 and 4125427
• Two-piece set designed for exact fit
• Fits 1942-1948 Buick Roadmaster Series 70 and Super Series 50 models
