Hey Scott,
Here is a photo of the Green Sud, courtesy of Ray Gulson.
I wouldn't worry about trying to find it though....

I'm not 100% sure about the story but the Group C Sud was purchased by Andrew Leithhead and Phil Whalley in the 80's and it ran in 6 Hour events and the like until it was rolled at Oran Park I think in the late 80's. The car was reshelled and I think (though I'm not totally sure) that there was a continuation of the Group C logbook.
I believe this Sud was then "retired" when Leithhead brought his Group A GTV6 (another sad story...

) and all the good bits like the close ratio Autodelta gearbox were dipsersed among the "faithful." The shell was then sold to another Sud racer with the logbook. It still exists in I believe average condition but whether it can be built up into Group C Bathurst spec and whether it would get a Certificate of Description (despite the Group C logbook) is another question.
Gulsons also took a silver Sud (on Momo Vegas

) to Bathurst in 1981 but it failed to qualify. And no, I have no idea what happened to that one. Probably sold on the lot to a Canberra suburban housewife...
