Doors for my 51 truck

[Midgets50]

Hello all,
ive got a 51 3600 chevy truck and im getting down to needing doors to finish the build before it goes to be wired and painted. is it easier to try and find some cheap doors or should i try and repair mine. current doors have bottom rusted out and everything is froze up. missing window cranks and all internal parts. would it be easier to have a solid window instead of a wing vent in my current doors?
Thanks in advance
