Which Glass Option Is Right for Your Classic Build?

When it comes to classic car restorations or custom builds, the glass you choose isn’t just functional—it defines the look of the entire vehicle. Whether you’re building a factory-correct Camaro or a smoothed-out pro-touring C10, your choice between stock-style glass and flush mount glass is a key part of the final result.

Two Great Options. Two Different Outcomes.

At Fesler, we believe flush mount glass offers the cleanest, most refined finish for modernized classics—but that doesn’t mean it’s right for every build. Some restorations call for the classic charm of factory-style trim and gasket-mounted glass. This post breaks down the differences so you can make the right call for your project.

What Is Stock-Style Glass?

Stock-style glass refers to the original mounting design used by GM and others during the muscle car era. It uses a rubber gasket or trim to hold the windshield or rear glass in place, with visible stainless trim often surrounding the edge. This gives a distinctive “stepped” look that many purists love.

Best For: Factory restorations, period-correct builds, shows with OEM judging standards.

What Is Flush Mount Glass?

Flush mount glass eliminates that stepped edge and trim. It’s designed to sit tight and level with the surrounding sheet metal, often bonded in using a modern urethane method. The result is a smooth, almost factory-modern look—more like what you'd see on a modern performance vehicle.

Best For: Restomods, pro-touring builds, SEMA-quality customs, or any car where clean lines are the goal.

Key Differences: Stock vs. Flush Mount

Feature	Stock Glass	Flush Mount Glass
Look	Period-correct with trim/gasket	Clean, smooth, modern finish
Mounting	Gasket or trim-mounted	Bonded with urethane adhesive
Sealing	Good with proper install	Excellent with modern adhesive
Difficulty	Easier for DIY	Best installed by a pro
Visual Appeal	Authentic, classic look	Custom, high-end appearance
