Grant (The maker of steering wheels and helmets) made the boxes for Joel-or most likely Joel bought the boxes from them and added his own decal. Grant was selling these ignition boxes back in 1968 and they were black and were 100% identical to the boxes Joel sold.

I always thought Jacobs did not even start as a company until 1973-1974 ish anyway-and they said they got their their start due to the 1970's energy crisis?.

Jacobs was the one that probabaly got the box molds from Grant when they got out of the CD ignition business and concentrated on steering wheels.
