Could some kind soul please tell me if they know of a proper alternate seat cushion to replace the standard bottom jump seat cushion found in the back of an 88 Series IIa station wagon? I have the 4 originals but, the fabric's shredded and I'm wondering if Land Rover ever produced another seat cushion for this or another vehicle with the same dimensions that I can use as an alternate. Our hosts and a few other purveyors of cushions only seem to sell the whole seat (back, bottom, brackets, hinges, etc.) but, I just need the bottom cushion. I'd prefer to just have the upholstery replaced on the cushions but, for the quotes I'm getting from local boat/automotive upholsters, I might as well just buy a new cushion.

thanks.
