I was jealous of Dave's pictures, so I threw the digicam on the ground and it started working again. Here is the upper deck I made for my tc3:

It is the only one I have ever seen that does not limit the access to the diff halves (due to my integrating it into the corner braces.) It is also still very low on the chassis, less than 4 mm above the shaft. It is very functional at making the chassis extremely stiff, especially after moving the battery in.

You can also see my other mods: serpent shocks, custom battery brace, and custom motor clamp.
