Ok I emailed PCNA and this is the quote I got back
"Equipment for California refers to the fact the vehicle met the safety standards for California. Before 1980, Standard Emissions did not exist through California still had requirements manufacturers needed to meet. This option confirms your vehicle met those safety/emission standards."
"Option group K22 included the below options
Bumpers w/ Impact Absorbers - F/R
Forged Alloy Wheels
Stabilizer Bars F/R
Oil Tank, Oil Level & Oil Pressure Gauges (Metric or English)
Sport Steering Wheel 380mm"
