Hi Bob, as others have said there is no manual as such for your Morgan although you will be able to obtain Haynes manuals to cover your relevant engine or gearbox. However there are factory parts manuals, often more useful than workshop manuals, available in PDF form, all of which have links on TM. Perhaps someone more computer literate than me can provide the link. Failing this pm me as I do have them somewhere on my office p.c.
GoMog is highly recommended too!
