Will this bolt straight to my existing mirror bracket?

Yes—it uses factory mounting points. Unbolt the old mirror and bolt this one in place. No drilling or bracket modification needed.

Does the manual adjustment cable work the same way as the original?

It's a direct replacement, so operation is identical to what came on the vehicle. If your original cable was damaged, inspect it before installation.

Can I return this if it doesn't fit?

Test-fit it before committing. If there's an issue, contact support with photos and your vehicle details to confirm fitment before requesting a return.
