Does anyone have an original starting crank for a pre-1954 Chevy 6 cylinder? If so, can you tell me what diameter the shaft is supposed to be, and how long the two protrusions on the business end are supposed to be? From the bumper tab and harmonic balancer, it looks like the shaft should be slightly less than 3/4 diameter, and the little nubs should be no more than 1 1/4 inches in length. Please confirm.
