They were essentially two year only and not a lot of cars got them. SO, you have rarity and scarcity to contend with. The calipers, rotors and pads could also be sourced from Imperial. But you're still in the same boat.
Ill just say that the Cardone calipers were the last straw for me and why I machined caliper brackets and went with Wilwood. Im sure others have positive experiences but the ones I bought wouldnt stop leaking. Cardone wouldn't send out new seals. They wanted the caliper back and they'd either...
