if you mean a Haynes Workshop Manual they are easy to get off ebay.co.uk but there are a number of editions, the most recent edition is the best one obviously
I have a spare factory glove box manual, but nothing of any real depth in that
If your after something specific out of the manual let me know as I have Two Haynes Manuals here and can copy pages if that's any good
I also have the microfiche diagrams for the entire Opel Manta range with factory part numbers, again I can maybe help you there.
