Do these covers come with mounting bolts?

Mounting hardware is not confirmed with this set. Plan to use your existing door handle bolts or source stainless fasteners separately to avoid rust.

Will these fit if I've already replaced my door handles?

These are designed for factory door handle hardware. Aftermarket handles may have different bolt patterns — test-fit before committing to installation.

Does the chrome finish need any prep before install?

Chrome is ready to mount straight out of the box. Clean the contact points on your door handles before bolting the covers on to ensure a secure fit.
