Hello Ruxy, the question of rebuilt or reconstructed is as subject of some debade, and open to interpretation. At what point does a rebuild become reconstruction? I am not sure and would ask does it really matter. As to your comment "Using a MB engine rather than a Ford is hardly a true reflection of the marque", the Willys and Ford Jeeps were both manufactured with fully interchangeable parts. During their service life many Jeeps ended up with mixed Willys or Ford components. In the field they did not care about originality, so many Jeeps ended their serice life with different engines. You are right, if you are looking for factory delivered example, it should all match. Regads John
