Do I need a new receiver dryer or desiccant cartridge when I swap this in?

Swapping the condenser alone doesn't require a new drier. If your system is functioning and refrigerant is clean, you can recharge with the existing drier. Replace it only if you've had a major system leak or the system has been open for extended time.

What mounting hardware do I need to bolt this down?

The condenser uses factory mounting points and fasteners. Gather any OEM bolts or clips from your existing condenser before removal — they're reusable. No additional hardware beyond what's already in your engine bay.

Can I install this myself, or do I need a shop to pull a vacuum and recharge?

Physical installation is straightforward — disconnect old lines, unbolt, swap in the new unit, and reconnect. Pulling a system vacuum and recharging refrigerant requires EPA-certified tools and training. Most owners take it to a shop for that final step.
