914Rubber Glass Rear Window for Porsche 914 (1970-76)

PMB Performance, with 20 years of Porsche 914 expertise, is the top 914Rubber retailer, selling more SKUs than anyone. Our nearly two-decade partnership with 914Rubber ensures premium restoration parts. The 914Rubber Glass Rear Window (Part #91454501210) is an OEM-quality replacement for the Porsche 914 (1970-76), complete with a reseal kit for a factory-fresh, leak-proof install.

This tempered glass rear window matches the original’s dimensions and curvature, ensuring perfect fitment. It includes an 8 mm x 15' butyl cord and two glass setting blocks (Part #91454190710) for a secure, watertight seal. The butyl cord’s tacky, flexible rubber resists vibration and thermal expansion, while the blocks prevent glass-to-metal contact, reducing stress cracks. Compatible with Porsche 924, 928, 944, and 968 rear window frames.

Installation requires the included kit, isopropyl alcohol, lint-free cloth, plastic trim tools, and gloves. Remove seats and back pad (unscrew base, slide down), clean the frame, and treat any rust. Press the butyl cord into the frame channel from the bottom center, overlapping ends 1/2 inch without stretching. Place blocks at the channel base. With a partner, align and press the glass into the cord evenly. Cure for 24 hours at 60-80°F, then test for leaks. Warm the cord if below 60°F, and work slowly at corners. A 914 owner said, “Crystal-clear glass, zero leaks—914Rubber nailed it!”

Our 20-year 914Rubber partnership delivers unmatched quality and support.
