Lando, I have a full database of all the 968 cabs. There were 72 968 cabs produced in black in 1993. I would have to check to see how many of those also had cashmere interior. What makes you think your car had a factory installed rear seat? Was it a canadian spec car (they do have the rear seats). If you give me some more information on your car i could probably get you the VIN. What other options? 6spd or Tip?
I modified my Cab for the 4Seat conversion. I now see I am not the only one, but it was the first. I posted step by step instructions on the old 968.net If anyone can help me find my car I would appreciate it.
Those "wrong" numbers have been published in Morgan's 968 book so they are out there. My data is new car production data for all the 968s right down to each specific 968. i have a complete cab database and I'm almost done with the coupes. Let me know if you have any questions.
