Not sure what you do not like about the Haynes. You may not like the Bentley as well. Have had the Haynes longer so I think that is why I go to it first. Usually gets me on the right track. The Bentley may be a bit more detailed at least it seems that way to me.
Of course, when all else fails we are very fortunate to have so many excellent references on the Internet. The archives of some forums are huge, some have excellent libraries, and some just have a bunch of great people on it, i.e. this one.
Ask Santa for the Bentley. It makes a great stocking stuffer for the MGBer in the family. /ubbthreads/images/graemlins/thumbsup.gif
