Even though the bus was cracked it was NOT loose , I couldnt pull it along the shaft at all so I think its still fine , given the other linkage has the same rattle its bloody odd , it does it in 3rd and 4th only , I only have to just touch the stick and it stops , I will try and get a video of it for you guys.
The bush on the rear is also perfectly in tact , that was my guess that it would be touching metal but its a long way off.
I can also leaver the stick a couple of mm off the tunnel and the rattle is still there.
