[Modshack]

I did this a few years ago for my C6, but should work just fine for the C7.
Hangers/Brackets available cheap at most Lowes or Home Depots.
Sturdy, simple. Mount top brackets to hold the top to the handle recesses.
Position lower bracket to handle some of the weight. Done

Simple and efficient, not to mention very reasonably priced Modshack! Thanks for posting.
