What is true about window regulators in vehicles?

Window regulators are mechanisms that control the movement of vehicle windows. A crucial aspect of installation is the method of securing these regulators to the vehicle structure. They can be installed using either bolts or rivets, depending on the design of the vehicle and the specific regulator being used.

This versatility allows for different assembly methods based on manufacturing standards and repair needs. For instance, in some vehicles, regulators might be designed to be easily replaced, requiring bolt installation, while in others, a more permanent riveted installation might be utilized. This dual capability means that when performing repairs or replacements, a technician has the option to choose the most appropriate installation method based on the situation at hand.

The other options suggest a limitation either to bolting, riveting, or a permanent attachment, which does not reflect the adaptability and practical application seen in actual vehicle repair and assembly.
