Will this bolt to my existing AC lines without modification?

Yes. This condenser uses factory connection points, so your OEM lines and fittings connect directly. No adapters or line work required.

Do I need to pull a vacuum and recharge the system after install?

The assembly ships sealed. Your AC system will need a full evacuation and recharge after you install it — that's standard for any condenser swap. Have a shop handle the refrigerant work if you're not equipped.

What if my old condenser had a receiver-drier attached — does this one?

This is a condenser-only unit. If your original system uses a separate receiver-drier or accumulator, it stays in place. Confirm your setup before ordering to avoid a mismatch.
