I was looking at it today, and asking myself what is missing, and realized I completely forgot something very important for this car... a battery box.
So designed one, and am printing it now hoping it fits.
Based the design on the Jammin SCRT10 battery box I have in my E-MT with a few minor changes.
Waiting till the new axles come in till I really get started on the body mount issue.
EDIT:
picture of the battery box installed. I didn't get one of the holes location exact which was off by 2mm's so I just drilled a new one. I also added 2 more to make it more secure. I'll prolly update the original file eventually with the changes, but I'm not remaking it now.

battery fits well.
