Specifications Type: Rearview Mirror Bond-On Button Material: Steel Function: Windshield-Bonded Mirror Mount Application: Interior Rearview Mirror Mounting Vehicle Fitment Ford (Multiple Models) Cross-Reference Numbers Ford OEM: F1TZ-17698-A SMS Part#: 19393 What is a rearview mirror button and what does it do? A mirror button (also called a mirror mount or mirror bracket) is a small steel piece adhesive-bonded to the inside surface of the windshield. The interior rearview mirror clips onto this button. During a windshield replacement, the button must be re-bonded to the new glass so the mirror can be reinstalled. What adhesive is needed to bond this mirror button? A dedicated mirror button adhesive kit is required — standard windshield urethane will not work. Two-part epoxy-style mirror bond adhesives are available at most auto glass supply distributors. Follow the adhesive manufacturer's instructions for surface preparation, cure time, and temperature requirements before reinstalling the mirror. What is the difference between this button (19393) and the adapter bracket (19498)? The 19393 is a steel button that is bonded directly to bare windshield glass when no button is present. The 19498 is a nylon adapter for use when replacement glass already comes with a steel button pre-attached. If your replacement glass has a button on it, use 19498. If the glass is bare, bond this button to the glass first. How long should I wait before reinstalling the mirror after bonding? Cure time depends on the specific mirror button adhesive used, but most manufacturers recommend a minimum of 15–30 minutes before attaching the mirror, and longer at lower temperatures. Always follow the adhesive manufacturer's stated cure time and avoid applying stress to the button during the cure window. Is there a GM equivalent of this mirror button? Yes — South Mountain Supply part 19394 is the GM-specific steel mirror button, cross-referencing GM OEM 20626174. The GM and Ford buttons differ in base plate geometry to match each manufacturer's mirror clip design. Use 19393 for Ford vehicles and 19394 for GM vehicles.
