Does any body no where i can find some info on a austin 3.0 gt overdrive (land crab ).please?

If you're asking about a model that was based on the Landcrab (Austin/Morris 1800/2200 range), the answer is that the car, the Austin 3-Litre was a replacement for the upmarket Austin Westminster model, and was not very successful. It was never offered as a GT. For more info, go to a href="http://www.austin-rover.co.uk/" rel="nofollow"http://www.austin-rover.co.uk//a
