Each Kit Varies. You must provide your own tools and equipment to perform the task. I do not include soldering instructions or board instruction, some knowledge is required to perform this job, do some research before tackling the task. Make a map (take pictures) of the Caps that you remove, it's values and where they went. This will help you in remembering where they go. Take your time, do not force the caps off or on. Clean the mount pads. Be gentle to your Retro Mac. For Photos of Logic Boards and other info head over to MacDat for references. I would post the link, but they get removed, so use your favorite search engine and type in MacDat net ToTs RETRO is not affiliated with MacDat, I personally think it is a really nice website, with lots of great information on Retro Macs All Caps come sealed in a bag, with the values and quantities so they are easily identifiable.
