I've completed the work now. Took me two full days. I was on it from 7.30am untill about 5ish on Saturday and another full day Sunday.
All I can say is don't attempt it unless you have some fairly decent mechanical knowledge/experience. Its not very easy mainly due to access, and takes a lot of patience.
Saying that the first times the worst, trying to learn/find out little ways of doing things.
Big thanks to MickKPM, Sideways Danny and Fred for all the help and advice. Made a big difference. And also to the lad who made the guide in the guides section, that helped alot too.
