Bought 4x8 sheet of .025 from Airparts. Didn't have metal brake so used rubber mallet method of bending instrumentation wiring support pans between firewall and panel. Bent against grain by accident, however do not believe will be a problem given the non-structural nature and very low weight of service loops of wiring the pans will support. The battery, contactor, and distribution bus is mounted behind the passenger seat. Battery location reinforced with .092 extruded L and wrapped tight with sheet metal to resist high g loads in sudden stop situation. Fabrication and planning of these items took a long time. Acquired a small sheet metal bender for the smaller brackets that the bus and the contactor are mounted on. Used .016 L-angle as "finger" to get appropriate bend radius on those items. Used rubber mallet to create flange that cheap metal brake design doesn't support.
