113-837-409AAL VW Beetle Left Vent Window Post - Aluminum (1958-1964)

Left Vent Window Post (Aluminum) – 113-837-409AAL

The 113-837-409AAL is an essential component for any 1950s or 60s Beetle restoration. The vent window post is the "backbone" of the window assembly; when the original steel units rust, they often swell, making the main door glass difficult to roll up and down. This aluminum replacement solves that issue permanently while providing a clean, vintage look.

This post includes the felt channel mounting area and the necessary hinge points to interact with your existing vent wing frame. Because it is aluminum, it is significantly easier to work with than chrome-plated steel if minor adjustments are needed during the installation of new window rubber.

Installation & Maintenance Tips

• Seal Replacement: Since the vent window must be completely disassembled to replace the post, this is the best time to install a new Vent Wing Seal and Upright Seal to ensure a leak-free result.

• Felt Channel Prep: Before installing, ensure your Window Guide Felt is properly seated into the rear channel of the post. A small amount of weatherstrip adhesive may be required to keep the felt from sliding down over time.

• Avoid Over-Tightening: When riveting or bolting the post back into the door frame, be careful not to overtighten the fasteners, as aluminum is softer than the original steel and can deform if excessive force is used.
