Description

1986-1996 C4 Conv Body Lock Pillar Weatherstrip Seal Right Rear 14100366 - OEM Number(s) (14100366)

Restore a factory-tight seal where your convertible top, door window, deck lid, and lock pillar all meet with this right-hand rear body lock pillar weatherstrip, reproduced to original GM Part Number 14100366 specifications. Designed exclusively for 1986–1996 C4 Corvette convertibles, this weatherstrip installs along the upper section of the RH body lock pillar, tucking cleanly beneath the plastic trim panel and securing with OE-style push pins.

Constructed from long-life EPDM rubber, it provides critical sealing at one of the most leak-prone junctions on the C4 convertible body—helping to keep out water, wind, and road debris while preserving interior comfort and appearance.

Weatherstrip Care Tip
Weatherstrip seals are prone to drying and cracking—especially on older Corvettes. Regular maintenance with non-petroleum dielectric silicone grease keeps rubber seals elastic, prevents sticking, and protects against UV damage and extreme temperatures. Apply a small amount to a soft cloth and wipe over rubber seals monthly. This treatment extends the life of weatherstrips on doors, window seals, sunroofs, trunks, hoods, and convertible tops. Avoid petroleum-based products, which accelerate deterioration and surface cracking.

Because Details Matter
Without this seal in place, even a freshly restored C4 convertible is vulnerable to leaks and cabin wind intrusion. Restore original weather protection with this USA-made, convertible-specific replacement.

Under the Straw Hat – Restorer’s Insight
The RH and LH rear lock pillar weatherstrips are not interchangeable. GM used unique moldings for each side to match the curve and tension points of the convertible top and deck junction. Installing the correct part ensures your trim fits flush and your seals compress evenly.
