Haynes Classic Manuals – own an authentic piece of Haynes’ heritage
Haynes Classic Manuals are the product of Haynes technicians performing a stripdown and rebuild of thousands of vehicles over decades in one of our world-renowned Haynes Workshops. Crafted from original material from the Haynes vaults, this manual was first printed more than 30 years ago and is now available exclusively as part of our Classic Manual category. The legendary mechanics and authors who created these titles may have since retired, but we have carefully maintained the original information so that you can purchase a brand-new edition for your classic or modern classic vehicle.
NOTE: Whilst in some rare cases the images may have been affected by the passing of time, the advice, diagrams and comprehensive step-by-step instructions based on a full stripdown and rebuild in one of our Haynes workshops remain as relevant today as when the manual was first published.
