914Rubber Glass Setting Block for Porsche 914 Windshield and Rear Window
Properly install your Porsche 914’s windshield and rear window with the 914Rubber Glass Setting Block (part number 914.541.907.10), designed for all 914 models from 1970-76. This reproduction rubber spacer sets the glass at the correct depth during installation, ensuring a secure and weather-tight fit. Four blocks are required per car—two for the windshield and two for the rear window—compatible with 1.7L, 1.8L, 2.0L, and 914/6 models.
PMB Performance, with over 20 years of Porsche 914 expertise, has partnered with 914Rubber for nearly two decades, selling more 914Rubber SKUs than any other retailer. Crafted from high-quality, UV-resistant rubber, these blocks withstand moisture and temperatures up to 160°F, unlike factory spacers that may degrade. Each block ensures proper glass alignment, preventing stress cracks or leaks in the 914’s 1,980-lb chassis, as noted on 914rubber.com.
Improperly set glass can lead to water ingress, risking rust around the windshield frame or rear window channel, or cause glass rattling. Installation involves placing the blocks between the glass and body, using 477.898.011.A butyl cord for sealing, as recommended in 914rubber.com’s tribal knowledge wiki. Pair with the 914.541.921.11 trim clips and 914.541.213.10 rubber molding for a complete refresh. Regular inspection during glass maintenance ensures a lasting seal.
