I recently purchased the Heritage Motor Centre CD - "MGB & MGB OriginalTechnical Publications". They have them to cover different year ranges. The CD has parts publications, worshop publications, and owners literature for various years. In my case, I have a 76 roadster. The Bentley manual , that covers 1974-1980, has the owners manual for a later model rubber bumper car, and it doesn't match my car. But the CD has the owner's manual for my car. The CD is available from Moss for $30. Well worth it in my opinion.
