Does anyone know if the cog on the CAS which goes into the Cam shaft

Can be replaced separately to the actual CAS itself? If so this would be very very very helpful.

Also if anyone has a spare TT cam shaft, i beleive it is the "exhaust side" of the right hand side of the motor when facing the car from the front to the back. Fleet has given me an old NA one however apparently I need something special to install this, being the thoroughly unspecial person I am I would prefer the simplicity of a direct fit TT cam shaft. I will also post this in wanted section.

 

if you luck out, I think the cam sprockets are pretty cheap.

 

Cam sprockets? which part are they?
