there are a couple of documentation items on ebay, a 1992 fact book showing the models and options for the year-

and the breathtaking prices...

also the 1993-5 technical service bulletins- (this is from the 1993)


showing the lack of representation of the 968...

the manuals are a little pricey ( maybe worth it for a 911 owner ) but pretty interesting...
