Will this glass fit into my existing mirror housing without modification?

Yes. This uses factory mounting points — it bolts directly to your current mirror frame with no frame bending or drilling needed.

Does this come with the mirror motor or frame?

No, this is the glass lens only. Your existing motor and frame stay in place; you're only replacing the glass panel.

What if the glass doesn't seat perfectly once I receive it?

Test-fit before final install. If adjustment is needed, loosen the mounting bolts slightly to shift the glass into proper alignment, then re-tighten. If the fit is off due to damage or defect, contact support with photos.
