Trunk Decklid Weatherstrip

This Trunk Decklid Weatherstrip is crafted from top-quality EPDM sponge rubber, designed as an exact copy of the original to provide a superior fit and seal around your 1965-1966 Ford Mustang Fastback trunk decklid.

The strip runs the full perimeter of the decklid, ensuring a tight seal to keep moisture and debris out. Installation involves gluing the weatherstrip directly to the trunk decklid; you may need to trim the length to fit your specific vehicle perfectly.

• One continuous strip covers the entire trunk perimeter.
• Can be bonded end-to-end with Loctite Super Bonder 495 for a seamless one-piece seal.
• Glue-on installation for a secure hold.
• Made in the USA and guaranteed to fit.

For easier installation, consider our peel-and-stick alternative (part number 20-2859-WT), dimensionally identical but with adhesive backing.

Adding the Weatherstrip General Installation Kit to your order provides all the tools and adhesives you'll need for a proper install. Check the matching vehicles tab to confirm compatibility.
