So sucking it all in, some bits arrived in the post:
First up, the Hepco Becker bash plate. It had some sharp edges, so a little time with the file seemed like a good idea. Fits well, and its all welded. The marketing pics show its rivetted, but welding works better for me I reckon. It doesn't contact the engine underneath and where the lug is on the LHS, there is a hole in the plate. I thought about cutting the lug off the cases but couldn't quite bring myself to do it, yet.
The standard plastic deflector.
You can see the lug through the hole in the plate, and hole below it. in case.
No protection for the water pump and hose though.
