So I'm confused about the Optical Drive Bracket, the one that originally held the DVD-CD drive. I had an awful time remounting the kit into that bracket as the screws didn't line up correctly. I finally got everything to fit, less one of the four holding screws. Did anyone else experience this problem? I would have expected a much better alignment for this assembly considering the quality of the iFixIt site.

For the record, the upgrade went fine with a SanDisk Extreme II 480GB SSD, but that one step was next to impossible, and not covered in any detail by the instructions.

By far this was the most difficult cable to reconnect. I enlisted a second person to hold the display after I unscrewed the power supply (Torx 10, 4 screws) and was able to give my fingers adequate room to securely reattach it. There's no need to do this when disconnecting the power supply, but it would take more nimble fingers than mine to reattach it without loosening the power supply.

Thanks for the instructions. It made everything easy to do as your instructions were excellent. I was working on a first generation 1TB TC (A1254) whose drive had gone bad. I removed it and decided not to replace it. I'm now using the TC solely as a Airport Express to extend my wireless signal throughout the house. It fired up perfectly and has the added advantage of running much, much cooler.
