Keep the Elements Out: 1968-1969 Corvette C2 Coupe T-Top Inner Left Side Weatherstrip Seal

A leaky T-top can turn your Corvette from a dream ride into a damp disaster. If wind noise, water leaks, or deteriorating seals are ruining your driving experience, it's time for a factory-accurate weatherstrip replacement.

Precision Fit for a Factory-Tight Seal

Designed as a direct replacement for GM part number 3935521, this right-side inner T-top weatherstrip is engineered to seal out water, wind, and road noise—just like the original. Over time, rubber seals dry out and crack, compromising your Corvette’s interior. Replacing them is crucial for preserving comfort, protecting your interior, and preventing costly water damage.

Key Features & Benefits:

  • Exact Fit for 1968-1969 Corvette C2 Coupe – No trimming or modifications needed 
  • Seals Out Water & Wind – Keeps your cabin dry and quiet 
  • Durable, High-Quality Rubber Construction – Resists cracking and deterioration 
  • Matches Original GM Part #3935521 – Ensuring an authentic restoration 
  • Inboard 3/4 section of correct 2 piece 1968-1969 design
  • Made in USA

Why This Part Matters

Your Corvette’s T-top is a standout feature, but without a proper seal, it can become a major weak point. Worn-out weatherstripping lets in water, wind, and road noise, leading to an uncomfortable and potentially damaged interior. Replacing it now ensures your Corvette stays as dry and quiet as it was meant to be.

Restore the Ride, Protect Your Investment

Don't settle for leaks and rattles—upgrade your T-top weatherstrip today and enjoy a quiet, weatherproof ride once again!
