Assuming they are the original engines everything should be simular. The only exception I can think of was that the year the glow plug type was changed? Was it a mid year deal? The preffered glow plugs are the pencil type. I would have a quick gander to make sure. Check that replacement engine over very carefully. A compression test might even be a good ideal if possible. The indicated total milage on the doner car is probably way off. There are exceptions but do not count on it. A 123 mercedes with 140k will have an interior basically almost exactly like new in most cases. Again just my opinions. Best of luck.
