Hi guys I've just changed the transfer box cover seal and refilled with oil on my 1983 swb series 3 2.25 deisel and then went on to do the gear oil. As i removed the drain plug 4 thin strips of metal fell out it looks like they have snapped in half, 2 of which have a slight shiny groove in them .Am i right in thinking that this is the clutch detent spring and if so how important is this Would appreciate and feedback or help as im just about to mot it after part restoration Many thanks dom.
