Writ of replevin is best suited for this situation.
It allows Auto Rebuilders to apply to have the parts seized since there was a legal agreement which is now overridden by an illegal arrangement between the supplier and the buyer paying more money.
The court application will seize the goods while making investigations into this matter then provide a ruling once the decision has been reached. Writ of replevin is often used to take property from a person who attained it wrongfully or legally and returns it to the rightful owner.
