I've just stripped mine out this afternoon 
The spacer is 15mm outside diameter and 4mm thick and is made from stainless I think as its not magnetic!
Check carefully inside the exhaust because the first time I stripped mine out I had the same thing and thought it was missing but on closer inspection I found it inside. It had dropped off when I pulled the valve out.
After I had found it I struggled a bit to get it back and that is how I know its not magnetic!
If you don't find it I would check the diagram again I think its the bush that's £35 not the spacer!
Good luck!
