Not having seen it my self, but manufacturers try to use as many parts from the original chassis/vehicle as possible. Not only to limit costs, but to retain the oem features making parts easier to source. AL-KO who make chassis for motor homes are an excellent example as they construct a complete new rear chassis of their own design, they do however use all the suspension goodies off the original vehicle so that you can go to the manufacturers dealers and obtain the spares easily.
When you get your spares, do report back so we have information for other owners.
