American-Made Quality. Designed, prototyped, molded, and manufactured in North America for OE-plus geometry, clarity, and fit. This is not import glass resized to approximate fit. This is glass engineered from the ground up for the Squarebody platform.
Kit (front and rear) fits 1973–1987 Chevy/GMC C/K Squarebody pickups. Windshield-only also fits 1973–1989 Blazer, 1973–1991 Jimmy, 1973–1991 Suburban, and 1973–1991 R/V pickups.
Give your Squarebody the modern trim-delete, flush-bonded look without compromising fit, safety, or legality. Unlike oversized import glass that often needs to be sanded or "massaged" to fit, Fesler Flush-Mount Glass is engineered through iterative prototyping and multi-vehicle verification to seat precisely in the OE opening. Front windshield is DOT-certified laminated glass. Rear is tempered glass. Both feature an OE-style green hue and block 99.9% UVA. No exterior trim or rubber weatherstrip required.

EVERYTHING YOU NEED TO INSTALL RIGHT.
A real talk on fitment, install timing, and what separates a clean Fesler bond from a fight with your installer. Read this before you order, and again before you cut tape on the crate.
FITMENT, STRAIGHT TALK.
Our glass is engineered and manufactured by Pilkington, an OEM glass producer that supplies new vehicles sold today. Same float-glass process. Same tolerances. Made on the same kind of production line that builds glass for modern cars rolling off dealer lots right now. This is real automotive glass, not import stock resized to approximate fit.
On a properly prepared body, it drops in. The reality with classic cars: these vehicles are 50 to 70 years old. Decades of accidents, racing, repaints, and subtle sheet-metal shifts mean some openings have moved over time. The glass is the constant. Your car's opening is the variable. Minor adjustment or light bodywork is occasionally part of a real classic build, and that's true for any precision part going on a 60-year-old car.
Best results come from planning glass into the bodywork phase, not after final paint. If you skip that window and bond glass to a body that needs work, you're asking the glass to do something it was never engineered to do.
WHERE ARE YOU IN YOUR BUILD?
Build timing matters. Here's a quick read on where flush-mount glass fits into your build sequence, and what to expect at each stage.
Just Starting
Shell on the rotisserie, planning the build. Order your glass now and bring it into your bodywork plan. The opening can be massaged to spec while the body is still in metal stage.
In Bodywork
Doors and fenders hung, panels gapped, primer or pre-paint stage. Test fit your glass now, identify any opening corrections, and address them before final paint goes down.
Painted, Build Nearly Done
Body and paint complete, working through interior and final assembly. Test fit early. If the opening needs adjustment, you'll want to address it before bonding glass to fresh paint.
THE 12-STEP INSTALL AT A GLANCE.
Full Walkthrough →PREP & REMOVE
Protect the vehicle, remove the original glass, clean the channel down to bare metal, and remove the factory clips. The four steps before any new glass touches the body.
TEST FIT & BOND
Test fit with 3/8" fuel line, clean the new glass, prime the frit band, lay urethane, and set the windshield. The make-or-break sequence that determines fitment, seal, and final reveal.
CURE & FINISH
Support the glass through overnight cure, then optionally fill the body gap with weatherproof silicone for a clean, debris-free finished look. Don't drive or pressure-wash early.
CRITICAL INSTALL RULES
- Always urethane, never butyl. Urethane systems hold 600+ psi. Butyl holds 60. There is no comparison.
- Use proper urethane primer. Prime the frit band and let it dry. Skipping primer puts your windshield at risk of slipping loose.
- No glass cleaner on the bond area. Standard glass cleaner reacts with urethane primer and prevents proper bonding.
- Test fit before bonding. Use 3/8" fuel line in the channel to simulate urethane and verify fit and gap before commiting.
- Never touch primed surfaces. Skin oils prevent urethane from sticking. Apply, let it dry, leave it alone until you set glass.
- Cure overnight before driving. Don't drive or pressure-wash for 24 to 48 hours minimum after install. Refer to your urethane manufacturer's spec.
FOR PRO INSTALLERS Recommended
We strongly recommend professional installation by an NGA or AGRSS certified glass technician. The windshield is a structural safety component, providing up to 60 percent of a vehicle's roof crush protection and supporting airbag deployment.
Certified techs have the urethane systems, primers, suction tools, and bonding experience to deliver a weather-tight, structurally sound install. Bring this product page or our resource hub to your installer ahead of the appointment so they have the full reference.
FOR EXPERIENCED BUILDERS Advanced DIY
Fesler glass can be installed by a skilled, experienced builder who understands urethane chemistry, has done glass work before, and has a helper on hand. This is not a first-time project.
If you're going DIY: read the Tips & Tricks PDF cover-to-cover, work through every step in our install resource hub, use the right urethane and primer for your conditions, and have someone on standby to help you set the glass. Mistakes on glass install are expensive to fix.
