Let's return to body-on-frame construction, with a ladder type frame.
All frame connections will be bolted and electrically isolated. The
driver's side frame rail will be the positive bus bar and the passenger
side will be the negative bus bar. The capacitors will bolt directly to
the frame rails, as will the motor/generators at each end of the car.
Problem solved! In fact, the capacitors can act as the crossmembers, so
no actual crossmembers will be required.
Make sure to throw the main disconnect before placing your jack stands.
