Rear pop-out vent window hinge repair set for BMW E21 and BMW E30 coupe models, designed as a repair solution for the commonly broken hinge body of the rear side vent window mechanism. Instead of replacing the complete expensive OEM hinge assembly, this set replaces the failed plastic hinge body with a newly manufactured reinforced version and converts the original riveted construction into a serviceable bolt-together assembly.

The repair process is simple and allows restoration of the original rear pop-out window mechanism using the existing OEM hinge components. Included hardware replaces the factory rivets and provides a strong and reliable connection.
