Dutton Phaeton Radiator?

[Simonelite501]

Due to total ineptitude on my part, I have managed to puncture a perfectly good radiator. The axle stand which I had been using as a bonnet stay, and not remembered to move before I drove the car forward, has gone sraight through the rads brass bottom. The radiator came from a black cab, you know the London Taxi black cabs, and as such I would imagine that it will be difficult to replace, well there are no black cabs in any of the scrapyards local to me. Does anyone know of a replacement for this radiator? The car is a Pheaeton S3 and is powered by a 2 litre Ford Pinto. The obvious answer I supose would be a MK1 or 2 escort rad, but their as rare as hens teeth now, and brand new ones are pricey. I'm not sure of the Seirra's radiator would fit, any suggestions? I would prefer tried and tested set ups but any suggestions considered.
