Do I need to flush the AC system before installing this?

Yes. Old oil and debris circulate through a failed condenser and will contaminate a new one. Have a shop evacuate and flush the system before you install this unit, then pull a vacuum and recharge with fresh refrigerant.

Will this bolt straight to my truck without modifications?

Mounts at factory points — no drilling, welding, or custom brackets needed. Line connections are standard; verify hose routing before you torque everything down.

What comes with this — do I get mounting hardware?

You get the condenser assembly. Fasteners and o-rings for the refrigerant lines are typically sourced separately or reused from your old unit; confirm fitment with your truck's service manual before ordering.
