PSE...NOVA probably built like early to mid 90...they might still have a supply of parts but they might not...it's been a while. And if you have to pay them to machine a set your looking at the very least a 100 bill, maybe more....you may find someone on AT that has the bow hanging in the garage somewhere and you could probably pick it up for less money and swap the cams out.
