Direct answer: Yes. A kit is assembled from individually made components, so a silicone hose, a clamp set, a seal or a wear part can be supplied on its own. A replacement does not have to be a full kit, and the component is matched to the kit number the buyer originally ordered.
The request needs three facts: the kit number from the original order, the component that failed or is being renewed, and the model and year. With those, the component is identified against the same drawing the kit was built from. Where the kit number has since been revised, the original number is what the component is matched to, so the replacement fits the parts already on the vehicle.
Wear items are the usual request, since a hose, a clamp or a seal is renewed long before a pipe or a bumper. Metal sections and brackets are also supplied separately. If the whole kit is being renewed instead, the current number is quoted, and any difference from the original is stated before the order is placed.
