You can see here how the crossmember under the engine has had a "dropped" section welded into it to allow the engine to sit a little lower than it would have otherwise. Steering rack mounts have been fabricated.

Rather unusual trailing arm setup. Anti roll bar has been completely removed and replaced by trailing arm welded onto lower suspension arm.

Here is a better photo taken during change of front dampers.
The black stuff is not underseal. I scraped all this off one summer and painted whole chassis with POR15 from Frosts catalogue. This is a chemical anti-rust paint that is incredibly durable. If you get it on your skin you have to wait 2 weeks for it to "grow" off. I ended up in the heat of the summer wearing an old tracksuit top, eye goggles, hat, scarf wrapped around all the gaps between these, with rubber marigold gloves taped to the arms of the tracksuit top. I still managed to get small spots of the paint on my head. Since this grey paint is not UV stable I coated everything with black waxoyl just for good measure.
