Cunningham Machine 94-00 GMT400 Third Brake Light Foam Sealing Gasket

Replacement seal for the GMT400 pickup truck third brake light, made in partnership with 3rdMonkeyProductions. By now the factory foam seal has typically dry-rotted and crumbled — replace it to stop water leaks that can ruin your headliner. GM no longer sells this part; this is a 3D-printed replacement designed to solve that gap.

• Note: this is not an original or major-manufacturer-produced part — it is a 3D-printed reproduction seal
• Fits: 94-early 2000 Chevrolet/GMC C/K 1500/2500/3500 (GMT400)
