OK so I couldn't LEGALLY say T-Bone, so they are N-Bone skid plates.
My chassis ran an inch too long and I also needed some protection for the rear servo and steering system. Unlike the stock summit chassis the SummVee has a bulge at the rear, so the standard T-Bone would not fit. So creative thinking (and some blantant copying . . . . err . . . . . "borrowing") I am making my own "N-BONE" skid plates.
N-BONE initial card board mock up and measurements
front servo protection
rear servo protection
add some plexiglass, a "heat gun", rite dye, drill and screws and I should be in business
