I got them too!
I am actually working with the local shop now. The numbers for the cloth part is in the "84 Book" page 6 item "C 345" and the only place that we found it is at a place called "S-M-S" phone # 503-263-3535 . This "book" apperently is the bible for the interior guys. My guy is having me order 2 yards to repair my seats. I'm not going for show quality but, I do want a nice job. The leather part of the seats are apperently not a big deal to find something very close. I hope this helps, the cost is around 85/yd + shipping....
