Hi Toni thanks an absolute heap for those pics, finally i know what is what, i think the idiot who pulled my box apart told me i needed 2nd and 3rd actually means 3rd and 4th, as both synchros look like your pic of 3rd gear, i now remember 2nd is a 3 piece setup and looks nothing like 3rd gear.
looks like ill order a 3rd and 4th now
thanks again
Brad
