Thank you for the welcome, Gdads51! You are spot on—our pre-formed window run channel kits are currently passenger car-focused. However, developing dedicated kits for classic Chevrolet and GMC trucks is exactly why we are here! We’re working on the configurations for both steel-core and rubber window channel.I greatly appreciate the heads-up on Rule #2. Rest assured, we aren't here to push sales or spam the boards. We want to respect the community and learn. Best regards,Vic & Vic Sr.
