Hi Julian,
Like BDA, I don't have an S2 and neither have I ever taken photos of the door linkage. Mainly because it's a job that usually ends up with me cursing, sticking plasters on sore fingers and just so happy when it's all together that I just want to walk away and drink beer.
However, there are a couple of good images in the parts manual for the S2 & TC which show the general arrangement of the linkages so I combined the images to show both the view from both sides as a guide. Like BDA says, if you have the catch, handle and lock all mounted on the door there's really only one way they can go together. (the trick is doing that without wearing away the ends of your fingers on the little spring clips ! )
I would advise buying new clips if you can, they only cost pennies and I find it's much easier working with new parts wherever I can.
