New reproduction door glass roller bumper for Datsun 240Z, 260Z and 280Z, 1970-78, left side door glass. This part is made of stainless steel spring steel for a long lasting high quality part. This rubber guide helps keep tension on the door glass so it does not rattle. Your Datsun Z car may not have this part on it right now as these broke after years of being used and often were not available or re-installed.  See PT# 650-113 for right side.

* Part may require adhesive or clamping for installation.
