Will this mount to my existing mirror housing without any drilling?

Yes. This lens is designed to use factory mounting points — no drilling or bracket work required. Test-fit before final installation to confirm alignment with your specific mirror body.

Do I need to seal this glass to the mirror housing?

Mounting method not specified in product data. Inspect your factory mirror housing to determine whether it uses clips, adhesive, or a combination. Bring the old lens with you to the parts counter if unsure.

Is this lens tinted or clear?

Construction details and tinting are not confirmed in the product listing. Contact support with your vehicle's year and mirror location to verify tint options.
