Im not sure on how close 1200 and 1000 floors are, but I would think it will be the closest you are going to find as the 1200 is the next sunny along the datsun family tree.
Unfortunatley most 1000's that are ready to be cut up will probably also have rusty floors.

I would suggest making a cardboad template of what you want to replace and then make a replacement pan from your template.
Or... if you are lucky enough to have a 1200 available for reference, use the template to see how close things are.

If you make one and it is not 100% factory, it won't be seen once it is painted and covered over with carpet.

How much of the pan are you trying to replace Chris?

Ashley.
