The sunroof spanner is a bent allen-key type affair. My father also got his Patrol without a sunroof spanner. It was relatively easy to make one for him.
I'll take a picture of what it looks like, and what size the "allen-key" bits are. Should be relatively easy to make one up. Give me an hour or two, as I've got some urgent work to do, and then I'll measure it all up and post here.
