Controversial & Contradictive
Welcome to the forum Stu.
I can't help you with the cradle, but I'm sure one of the members can point you in the right direction.
By the way, I take it from the engine that your A4 is a B7 version, so maybe it would be best to post your question in that forum. You're always welcome in the B6 forum though, some of the "older model" posts might still interest you.
Enjoy your audi mate, there is a write-up on the 3.0TDi A4 in this months "Audi Driver" magazine, and it sounds like a sweet motor.
