I found this very detailed tutorial a while back - I ended up just replacing my rear window and not the whole hood so I have not followed it myself so cannot personally vouch for it's completeness or correctness, however, it is by far and away the most thorough tutorial I found during my search!

Also please note that it wasn't written by me, so credit should be given to the original author, whose name I can't seem to find! Either way, I hope you find it of some use.
