American-made quality: Designed, prototyped, molded, and manufactured in North America for OE-grade fit, clarity, and longevity.
Fesler Flush-Mount DOT glass gives 1964½–1966 Mustangs a modern trim-delete profile with OE-level fit. Each piece is prototype-built, molded, test-fit, manufactured, and test-fit again on multiple vehicles to deliver a clean, uniform reveal and a bonded, weather-tight install.
NO SANDING REQUIRED TO FIT. Some brands oversize glass and expect you to sand. Fesler prototypes, molds, test-fits, manufactures, and re-tests so your glass fits as delivered. You get what you pay for.

What is flush-mount glass?
Precisely sized glass sits within the OE opening with a tight, uniform reveal. It eliminates exterior trim and rubber weatherstrip and bonds in with an automotive FRIT band, primer, and high-strength urethane, producing an OE-style fit with no body modifications on most vehicles.
Polycarbonate vs. Laminated Automotive Glass — Know the Difference
Polycarbonate (“plastic”) windshields
- Not DOT-approved for public roads — not street legal for windshields.
- Prone to scratching, hazing, yellowing; wipers can mar the surface.
- Okay for track/off-road/display (where permitted), but not advised for street builds.
- Potential insurance and safety issues in a collision.
Laminated automotive glass (Fesler)
- DOT-approved laminated windshield for legal street use; tempered rear glass.
- Safety & clarity: resists penetration; remains intact under impact; superior optical quality.
- Durability: excellent scratch/UV resistance for long-term clarity.
- Model-specific fit for a clean, uniform reveal with our flush-bond system.

Important: Glass is non-returnable. If it doesn’t fit out of the crate, your vehicle may require body work. This is more common on some reproduction shells.
Dynacorn note: If you are using a Dynacorn body shell, our glass will not fit without substantial metal work and modification to the shell prior to install.
