help on I.D. of front axle

[nvrsatisfied]

Hoping i might be able to get a little help on this axle i just got. the guy that gave it to me belived it to be what he thought was a 50?? chevy truck. i have been trying to search via the matching numbers (24d204 or 24d2o4) i found on the front and rear of the main beam. with your help i hope to get it figured out so i can start a new adventure on either adapting disc or drums back to it and renewing other parts on it so i can use it on my new project.

thanks for all the help.
