I designed the drive platform to fit inside the LEGO greeblies.

I installed a C-Channel chris-crossed on top and bottom to stiffen the board

The 5 inch tall carriage bolts are for the battery hold down bracket and for mounting the body to the lower section. The 2 shorter bolts are for mounting the electronics board.
