Do these covers use the original door handle hardware?

Yes. These bolt directly to your factory mounting points using your existing hardware. No adapters or modification needed.

Will these covers fit over my current handles, or do I need to remove them?

You'll remove your old handles first, then install these covers in their place. It's a straightforward swap using the same fastening points.

Can I paint these if I want a different color?

ABS can be painted with proper surface prep. Sand lightly, apply primer, then use automotive paint. Follow standard automotive finishing steps for best results.
