Bill,
Most of the part sellers have manuals, this site and elsewhere, the good one, I think is the original Porsche Shop Manual, the ring binder one. In the online stores you can pay several hundred dollars for a complete set. I bought a complete set on eBay for $100.00, you might do a search there.
Also I purchased a PET, CD . The PET is the digital manual used for ordering parts, viewing parts, etc. for Porsche shops. It has exploded views of everything.......and part numbers to go along. It is a great research tool, it does require a PC format and a monitor with 1280x1024 resolution. I have the guy's e-mail if your interested.
Good luck and Happy motoring,
Chas.
