Additional NotesThe Tulip (original works rally ratio’s) type contains the first motion shaft, 2nd and 3rd gears and the laygear. Manufactured to the highest quality these have a large jump between 3rd and 4th gear and require a 22% overdrive to split the gap and create in effect a 6 speed gearbox. They are designed to use the BJ8 mainshaft and layshaft, which means that when fitting to earlier side and centre change gearboxes slight modification will be required.
