Thanks for your input

. as above you guys are saying that the spacer is soft and worn down, my slipper nut is tightened near almost all the way in for to get some bite. the car is brand new and noticed it was slipping in the house when i tried it holding spur/wheels etc before majour running.
can the b4.1 vts layshaft,slipper/spur/spring fit onto the 210.(whole assembly) im not a huge fan of the small spring, although obviuosly it does the job. the associated one looks better imo. im also aware that the b4.1 diff fits in also with some shimming, is anyone running that also. probably should have bought a c4.1 but at 95quid you cant knock them back and i like the rango.
just need some bite.
