I don't have a DIY for you but can assure you it is incredible simple. For the parts I would hit up fcpeuro.com. I am not affiliated but have used them for years to care for my wife's 550 and more recently parts for my m6gc. They are incredibly fast on responses and have yet had to send a part back.
This is a very helpful resource when doing your won repair work.
