Mastercraft boat made boats and often used instrument panels manufactured and assembled by ace industries. typically, ace would order electrical instruments and other parts and assemble them to mastercraft’s specifications. mastercraft decided to work with a different assembler, m & g electronics, so it terminated its relationship with ace and requested that ace deliver the remaining parts to m & g, which ace did. mastercraft then refused to pay for these parts, claiming that they were nonconforming. is ace entitled to payment from mastercraft for the parts?
