Thanks CharlesY, An exploded diagram would be ideal! Many Thanks!

The lever goes into the correct spot, I've had the linkage out and all appears to go in the correct place but the shaft doesn't engage reverse. I get the feeling it's something further into the box......

Reverse is to the left of 1st.

It goes into the syncro as normal but it doesn't engage reverse at all. No noise and no movement!!

Hi to all, am new here and am looking for some help! My Disco seems to have lost reverse gear... Ideally I'm after a Manual or exploded Diagram on the box so I can work out whats wrong! Thanks!
