The Wallace-translated Boxer service manual is available for $95 (http://wallaceferrari.com/). Mercian in the UK sells a 365 BB service manual for 35 GBP (call that $70). (http://www.mercianmanuals.co.uk/manuals_item.php?subject=Car&make=FERRARI&item=FER365GTSS) Has anyone seen them both and know how (if?) they differ? Are there any other interesting sources? Thanks, Alan Watkins
