The 911 and 912 Porsche, A Restorer's Guide to Authenticity II takes a
part-by-part, year-by-year approach to what an owner or prospective
buyer should look for when evaluating a 911 or 912 Porsche. For each
year, from 1965 through 1973, the author examines every change,
documented or not, of each model - and now including major mechanical
components. Included are the most accurate and comprehensive chassis
number and color/upholstery listings anywhere.
