Moulton agreed to manufacture molds for Lyn-Flex within five weeks. Moulton manufactured several molds, but they were imperfect. Lyn-Flex was dissatisfied with the molds, but Moulton believed the molds were still acceptable. Moulton manufactured and delivered the rest of the molds five weeks later than the delivery date specified in the contract. Lyn-Flex demanded that the molds be redesigned, but Moulton refused. Lyn-Flex refused to pay and obtained molds from another manufacturer. Moulton sued claiming that the contract had been substantially performed.

What is the Issue, Rule, Application and Conclusion?

what would the result would be different under standard contract law?

Thank you!
