Right, sorry it took so long had to get the assistance of my other half, there is nothing holding the mag assembly into place until you put the end plate onto the cage, you need to:
1, put the small plate spring onto the magnet carrier
2, place the magnet carrier into endplate the hole goes at about 5o'clock looking from reel seat upwards
3, the top end of magnet carrier goes under the slide control not inbetween as i thought, when the end plate is on the spring pushes magnets towards spool and the slider forces it away
4, the other plate spring goes on the hole about 1 o'clock
5, now the hard part getting it together onto the cage without it falling to bits
hope thats some help I remember the nightmarte I had when taking mine to bits the first few times.
