Several vendors offer timing chain kits that will include all that you will need. ECS tuning offers 3 versions. Be sure to buy a good tool to keep timing locked in place. Some have had problems going cheap. There are a couple of sources to rent a good quality tool. There are some good DIY step by step options with pictures, tips and help with organization on vendor websites if you are interested. I have read many posts and threads here that might also be helpful to you. They should be easy to find using the forum search function.
