Got the drawings done, here is the pretty version:
Top left is the motor mount, top right is the rear motor brace, middle is the upper chassis brace (ties the front shock mount to the rear shock mount), and bottom is the skidplate. Also, the cutout shown on the skidplate won't actually be a cutout, but where a 1/4" deep pocket will be milled out. The skidplate will be 1/2" thick black delrin.
