What you need is the Abus Granit X-Plus 54 (300mm shackle length). The shackle fits underneather the seat and the lock part sits next to the "tool roll" in the tool tray.
I happen to have a used example for sale very shortly!
As above, there's an Abus Granite that fits. The lock bar sits next to the tool roll in the tray (as long as you haven't got extra tools / an Autocom in there ). Nippy Norman sells the correct lock.
