healingbear,

Your link did not work for me but I think this is it (2.041 - 1913369):

Here is a better explanation of what is needed for the 1954 Hydra-Matic (H.T.) starter - a different drive end housing on a 49-54 car (non Powerglide) and 49-55 D.D. 6v starter or 1953 Corvette (special engine with Powerglide) starter (2.041 - 1913369 and 1925869).

Thanks for the Chevs of the 40s link. They also have the solenoid and other repair/replacement parts for the starter.
