Check the tech tips button for more details, but 3B is right. The Delco-Remy starter motors were the same for all engines, the only difference being the number of teeth on the starter motor drive viz-a-viz the flywheel.
Certainly, '41 through 53 Chevrolets all used the same starter motor--six volt, mechanical shift.
You say you are looking on some websites. Make sure everything matches. Always check model and serial numbers whenever possible.
You also haven't told us the details. Since you have a '48 GMC ton-and-a-half flatbed, I'm going to guess that it is pretty much original--6 volt electrical system, manual transmission, mechanical-shift starter (that's the one most of the fellers here call the 'masher starter' or 'stomper starter'), etc.
Confirm whatcha got and you will get a lot of help.
