I've one you can have. I can't see how to separate it from the generator though... all the wires look bonded into the cable gland where it passes through the cover. Guess it might be best to send you the whole cover/genny/pickup assembly and you can transfer the electrical bits to your cover (this one is a bit tatty having been slung down the road and lumiwelded by a previous owner, but it'll protect the electrics OK while in transit).
PM me if you're interested.
