🏁 1968–1982 C3 Corvette LOF Tempered Galaxy Glass T-Tops (GM Licensed)

For Corvette purists who want OEM-authentic restoration quality, the Galaxy Glass T-tops are the gold standard. Manufactured under GM license, they feature glass made by Libbey Owens Ford (LOF) — the original GM supplier — and carry genuine DOT safety stamps.

From outside, the panels have that legendary near-black smoked look that earned the “Galaxy” name, while still maintaining visibility and heat control inside the cabin.

Highlights:

• GM-licensed restoration parts assembled by an authorized manufacturer
• LOF-manufactured tempered glass — original GM supplier
• Deep smoked tint for style and heat reduction
• Frames and hardware built using GM Restoration Parts
• DOT-approved and stamped for safety inspections
• Reflects sunlight, reducing interior heat buildup
• 12-month warranty against defects in material or workmanship

⚠️ Fitment: choose the right set for your year

This listing has two options under Year. Pick the one that matches your car:

• 1978–1982 Set — a direct replacement. Bolts straight in, no extra parts needed.
• 1968–1977 Set w/ New Switch Plates for Retrofitting — the retrofit set. The switch plates are included with this option, so a 1968–1977 car needs nothing else.

Choosing the wrong option is the single most common ordering mistake on this part. A 1968–1977 car that receives the 1978–1982 set will not have the hardware needed to install it.

Why the retrofit is needed: GM changed the latch system partway through C3 production. From 1968 through 1977 the tops used two latches per side. Beginning in 1978, Corvette switched to a single front latch operating a rod that travels inside the T-top frame and locks into a switch plate on the B-pillar. Because these replacement tops are built to the later 1978–1982 design, an earlier car needs its rear locating plates swapped for the later switch plates — which is exactly what the 1968–1977 set provides.

Need switch plates on their own, or replacing a damaged set? They’re also sold separately as the 1978–1982 C3 Corvette T-Top Latch Rod Switch Plates (part #112s), a set of two covering driver and passenger sides.

Matching an existing top? If you’re replacing only one side and keeping the other, check the glass code first. Six different glass types were produced for the 1978–1982 Corvette, five of them loosely called “mirrored,” and no two of them match each other. The code is etched into the stamp on the outside rear corner of the glass. Send it to us at help@corvettestoreonline.com and we’ll tell you whether these will match your surviving panel before you order.

Why choose Galaxy Glass:
These tops deliver authentic OEM appearance, safety certification, and superior heat reflection — a must-have for collectors restoring factory originality.

🧰 Installation & Fitment Notes

• Both top options use factory latch and mounting points for their respective year ranges.
• Acrylic tops are lighter and easier to install; glass tops may require assistance due to weight.
• For 1968–1977 cars, select the retrofit set — the switch plates come with it.
• Always inspect and lubricate latch mechanisms before reinstalling.

🧽 Care & Maintenance

• Treat them like your paint job. Never dry-wipe the panels — use clean, wet microfiber towels, never paper towels.
• Clean acrylic tops with non-ammonia glass cleaner and microfiber towels.
• Avoid harsh chemicals or abrasives on acrylic or tempered glass.
• Wax or apply UV-protectant regularly to preserve clarity. A non-abrasive paste wax is fine.
• Store on padded racks or in protective bags to avoid scratches.
• Inspect weatherstripping annually for compression or cracks.
