64-66 Mustang Door Kit Custom Cut

The 64-66 Mustang Door Kit Custom Cut from DYNAMAT is a precision-engineered sound deadening solution designed specifically for first-generation Mustang door panels. This pre-cut kit is ideal for those restoring a classic Mustang or upgrading an original vehicle with modern acoustic comfort, effectively addressing common issues like door rattle and wind noise.

Utilizing a butyl rubber compound laminated to aluminum foil, this kit converts vibration energy into heat rather than amplifying it through the sheet metal. The material adheres directly to the door inner panels, reducing unwanted noise and vibrations that can occur at cruising speeds. The total weight of the kit is 6 lbs, providing substantial sound deadening without significantly impacting the door's swing mechanisms.

This kit is perfect for purists and restoration enthusiasts who want to maintain a factory-correct aesthetic while enjoying modern comfort levels. It is compatible with 1964–1966 Mustang models, including coupes, fastbacks, and convertibles, making it a versatile choice for various restoration projects.
