Ok I have had my flywheel re-surfaced and my AP clutch eventually turned up so now it has all been put back together and hooray I can select every gear and the car moves. I sat in the car for around 5 mins selcting all gears the more I did this the longer the throw became to select 1st until eventually POP it was like stirring porridge. I got out the car and the linkage on the side of the box had snapped/come apart OMG!!
I guess when I originally tried to force it into 3rd I snapped the cable but when I looked at the linkages they appeared to be in tact even when I moved them by hand I could see the gear lever moving and vice a versa the same thing when moving the gear lever.
So I have just spent the best part of 2K for nothing, I guess the clutch would of needed to replaced soonish anyway but still, and on top of that I now need a new selector cable (anyone have a spare)
