New Gas Tank, 4 vent tubes

I believe 70 was a "split" year. In CA 70 cars had the vent system. My old 70 440-6 RR was from out of state. I got stopped in one of the CA Nazi roadside checks once and actually had to show the idiots right in the service manual!! in the trunk!! that only CA cars had it. You could tell by looking the car had not been modified
