914Rubber Early Worm Drive Window Regulator Button for Porsche 914 (1970-72)

914Rubber Early Worm Drive Window Regulator Button for Porsche 914 (1970-72)

The 914Rubber Early Worm Drive Window Regulator Button is a precise replacement part for the early-style manual window mechanisms found on 1970–72 Porsche 914s. This small but critical component ensures proper engagement of the worm-drive regulator, restoring smooth window operation.

Made from durable, wear-resistant plastic, this button fits into the worm gear mechanism and acts as the interface between the window crank and the internal drive. A worn or missing button can lead to slipping, binding, or total failure of the manual window lift system—especially on early cars using this unique setup.

Key Features:

• Correct fit for Porsche 914 models from 1970 to 1972

• Specifically for early worm-drive style window regulators

• Restores proper window crank engagement

• Made from durable, high-strength molded plastic

• Prevents binding or failure in the regulator drive

Fitment Notes:
Only compatible with early 914s using the worm drive-style manual regulator mechanism. Later models use a different configuration.
