Hey Ron, the info that I gave you was out of my owners manual for a 92 240. The dealer had penciled it in, along with some other info about the car. In my salvage yard persuits, I have noticed that cars from 88-89 start to have the fine "tweedy" fabric instead of the wider, more corduroy stuff. It was used from those dates until the end of the series in 93. Its the stuff that I posted about before and to my knowledge it came in black/gray, tan, and blue. If you saw a car that was a 90, unless it was custom upolstered, it was probably the "Tricot plush".

Good luck in your "reseating"
Jonathan
