If that is the case, here is my read between the lines of what occured. Management wanted to "Cheapen" the car so removal of the resetable breaker was a no brainer, "Put a fuse in its place." Following that decision they discovered "Fuses are blowing, can't have that." Eureka, "Put a shorting bar in there, that won't blow." Problem solved.
I think you may have hit the nail on the head. Would it be safe to assume that the motor is the same from 1967-68-69? Then my red and green wires would be the same size as the 67 & 68. Then I should be able to put a 30amp fuse in there. How much worse could that be than the shorting bar?!?!
