Will this bolt up to my factory mounting points?

Yes. This condenser is designed to mount at the OEM support locations — no drilling or bracket modification required. Line up the mounting tabs and bolt it down.

Do I need a new receiver-drier or expansion valve when I install this?

It depends on why you're replacing the condenser. If the old one failed internally or leaked, flushing the system before install is recommended. A new receiver-drier is a good preventive move if the system sat open. Check your vehicle's service manual for the complete procedure.

Does this come with new O-rings or seals for the line connections?

The condenser ships with the assembly only — no seals or fasteners. Pick up fresh O-rings and any adapters you need at the same time to avoid leaks at the connection points.
