Absolutely brilliant, easy to follow and accurate, only improvement i can suggest is to use either use a magnetic screwdriver or stick a small magnet to your your screwdriver to make handling and positioning the screws easier.
I attempted this a few months ago without the guide and it cost £40 ($66 app.) to get it repaired after my attempt, this time £3.50 ($5.60 app.) big difference!!
Again many thanks.
