Here's a general overview of the process. This is NOT a comprehensive guide and should NOT be considered a substitute for professional instruction.
1. Preparation:
* Gather Supplies: You'll need the new plastic rear window, appropriate adhesive (typically urethane specifically designed for automotive glass), a glass removal tool (suction cups and a plastic razor blade are helpful), a clean workspace, safety glasses, gloves, and potentially a heat gun (for softening old adhesive). Consult the manufacturer's instructions for your specific plastic window for adhesive recommendations.
* Remove the Old Window: Carefully remove the old glass window. This will likely involve removing the interior trim around the window first. Use the glass removal tools to carefully work the glass free. Be very cautious to avoid cuts from the broken glass. Remove any remaining adhesive residue. Thoroughly clean the frame where the new window will be installed.
* Prepare the Frame: Inspect the frame for any damage. Repair any rust or damage before proceeding. The frame must be completely clean and free of any debris or old adhesive. Degreasing the area is crucial for proper adhesion.
2. Installation:
* Apply Adhesive: Apply a bead of urethane adhesive to the frame according to the manufacturer's instructions. This is crucial for a proper seal. Don't skimp on adhesive.
* Install the New Window: Carefully position the new plastic window in the frame. Ensure it's correctly aligned and seated before pressing firmly into place. You may need help to hold it in position while the adhesive cures.
* Secure and Cure: Allow the adhesive to cure completely according to the manufacturer's instructions. This usually involves a period of several hours or even overnight, with limited movement of the car to avoid jarring the window.
3. Reassembly:
* Reinstall Trim: Once the adhesive is cured, reinstall all interior trim.
Important Considerations:
* Professional Installation: This is a complex task best left to professionals experienced in convertible top repair. Improper installation can lead to leaks, wind noise, and safety hazards.
* Window Type: Ensure you purchase the correct replacement window, specifying the year, make, and model of your Mustang. The thickness and curvature of the plastic must be correct.
* Safety: Wear appropriate safety glasses and gloves throughout the process. Broken glass is sharp and potentially dangerous.
* Adhesive: Use the correct adhesive designed for this application. The wrong adhesive can lead to failure and leaks.
In summary: While this outlines the general steps, attempting this yourself is risky. The cost of professional installation is likely far less than the potential cost of damage to your vehicle or injury to yourself.
