If you are going to fit a sunroof you can still get a Webasto new today, made to the same spec, so it will look period.
And lets face it Webasto are the best, far better than a cheap plastic pop up one.
It will also make it easier to pop the warning beacon on the roof (to the side or in front, where there's still metal), saving you getting out and being splatted because those that know better than you have removed the safety lane.........
Best wishes,
Mike.
