Will these brackets work with my existing pulleys and belts?

These mount the pump and alternator — pulley compatibility depends on your specific pump and alternator model. Verify your pulley sizes and spacing before ordering if you're mixing components from different sources.

Do these brackets need any prep or finishing before installation?

Aluminum brackets ship ready to install. If you're painting your engine bay, you can prime and paint them to match. Test-fit first to confirm clearance in your specific bay layout.

What fasteners do I need to bolt these down?

Mount points are machined for standard fasteners — check your engine's service manual or test-fit the brackets against your block to confirm the bolt sizes and thread pitches required. Hardware not included.
