Do I need any special tools or hardware to install this?

Mounts at factory points using existing hardware — no drilling or modification required. You'll use what's already there. Grab a socket set and you're good.

Does this mirror come with the glass?

Yes, the complete assembly ships with mirror glass installed and ready to go. No separate ordering needed.

Will this work if my current mirror is electric?

No — this is a manual-only mirror. If your car came with power mirrors, you'd be replacing the whole assembly and losing that function. Confirm your mirror type before ordering.
