About a year ago I bought hilt pieces before deciding to add light. Now I would like to add light to my saber using the Module Wiring System. I may eventually upgrade it to better lights, but I don't plan to add sound in the future. Below is a list of pieces I already have and a link to my Wish List with the pieces I think I need to order. There are a couple questions at the end of the post. Thanks in advance for checking this over!

Pieces to Order: http://www.thecustomsabershop.com/Vi...6-1d8d0fe732ff

Pieces I Have:
• 12mm Anti-Vandal Momentary White Ring Switch
• 1" Blade Plug
• Corbin Battle Blade
• Covertech Clip
• MPS Pommel Style 4
• MPS Clip
• MPS Insert style 4
• MHSV1 Blade Holder Style 6
• O-Rings (17)
• Tap Handle
• Allen Wrenches

Questions:
• Do I have the right chassis disc? Do I need 2 of them?
• What size spacers do I need?
• What gauge wire do I need to order to wire the switch? I found several good tutorials on how to wire the switch, but they did not detail the pieces they used.
• Anything else I'm missing?
