I couldn't tell you. There was a company making complete lookalike rear ends to weld on at one point.
This is my best one with it's latest owner and coincidentally the one who built it. He part exhchaged it for a Rover 200 after spending stupid money on it including £4k on the engine and gearbox. As soon as he realised his error he looked for it everywhere to buy it back and fortunately he found it up for sale by me on a London to Brighton run.
