If the part in play can be referred to as an ‘assembly’, it will have a part no in the parts lists that doesn’t match up to the casting number. And it doesn’t take much, a Welch plug would be enough. The casting # and the part # would generally be the same on a ‘simple’ part (us old Boeing folk referred to those as ‘detail’ parts).
