one side caliper seals
two sets brake pads
all rubber frame bushings (machined from bronze)
rear shocks
battery charger changed to Quick Charge
two charger AC female plugs
motor bearing at transmission
both CV axles
four of six Dekka Gel batteries
added master switch like older GEMs have
DC converter (warranty)
removed heater (very poor range)
both front seats welded cracks
three sets of brake cables

ignition switch
both door cables
both door hinges
both pins for hard doors (machined from stainless)
