Mjit Posted April 27, 2019 Report Share Posted April 27, 2019 Worth downloading the Moss parts catalogue as there's a mapping of most nut/bolt part numbers to size/thread/spanner at the back - https://www.moss-europe.co.uk/media/pdf/SPI001.pdf Better still get a physical copy and lave it in the bathroom for reading material 1 Link to comment Share on other sites More sharing options...
