Book excerpt: Originally published in 1975, this manual was prepared in close cooperation with British Leyland Motors in order to provide complete, authentic maintenance and repair information. The Driver's Handbooks at the beginning of this manual are the handbooks that were provided with every new Triumph GT6, GT6+ and GT6 MK III. The Workshop Manual, making up the larger part of this book, is the official factory manual and was originally intended for use by dealer service departments. The publisher has incorporated additional factory procedures and specifications that have become available following the publication of the original factory information.

Including accurate and comprehensive service information for 1967-1973 GT6, GT6+ and GT6 MK III vehicles, this manual is an indispensable resource for both the professional mechanic and the GT6, GT6+ and GT6 MK III enthusiast. This manual contains complete coverage of all Triumph GT6, GT6+ and GT6 MK III models sold in the UK and North America during the model years 1967-1973.
