If I recall right, the dog bone can be got from andyspares quite cheaply, it is the top engine mount which is a renault only part. You are looking at something around the £20 mark for dogbone/gearbox lower link. The engine mount that has to come from reno is about £70, hope this helps you. Also they are surprisingly easy to fit, thought they were going to be awkward as hell but not as bad as you would anticipate.
