If there's nobody local, NAPA can get a rebuilt starter with a good warranty overnight in most areas. Just be sure to specify 6 volt. (1954 or earlier) There's a difference in the angle of the pinion teeth and the diameter of the armature shaft from the 12 volt units. The 6V has a shaft about 5/8" in diameter, while the 12V models are close to 1/2". If the original ID tag is still there, 12V starters have a red tag. 6V ID tags are black.
