I think and not 100% sure, but I think the brochure was wrong as they are printed far prior to production.
I still think it was a special service order as we did for govt vehicles. Those combinations were never public and listed as code and description. Maybe it was ordered and then canceled prior to delivery?
Example, I bought a never in service 1993 Mustang LX with police pursuit package that was traded in at Toyota (when I was big into Fox bodies) I knew what to look for. Here in Oregon they were white with black alloy wheels, ugly blue interior and drum rear brakes. They had a GT40 intake, Tremec 5-speed, gearing and posi. They were VICIOUS out of the box, but rarely ever in not seen that had not been in service. This was sold at Damerow in Beaverton and was a mis-order as agency wanted crank window, this had power, so they retailed it.
Also, I am asked every time I order carper "With or without rear 3 row seats" and the part numbers are different. I think I might order without and see what I get.
