Mate your trimmer is telling furphys, there are plenty of options in the right width, but is dependent on what your want and match to original. Foam backed is limited in width with widest being 165cm (which should be wide enough, just) that I could find. Most are not replacing with the foam backed stuff, but just using a felt like material to avoid further failure. The wholesaler indicated most Upholsterers are advising staright material over foam backed. I have just bought felt to do my sons and is just over 2m wide, so more than wide enough to do a D2. Going a much darker colour graphite to contrast, but they had some that was a very close match to original in 2m widths. They had plenty of options in stock and colours. Vinyl was a bit narrower ranging from 135cm - 165cm. Plus many other materials. That was from an Upholstery Wholesaler.
