1949 Plymouth 2 door frame swap

Hi,
I recently got me a ‘49 Plymouth 2 door with no frame, no suspension and no engine or trans. Already have a 273 I’m rebuilding and 904 trans for it but don’t know what frame I can use for it. If anyone knows any information or has done a frame swap on a ‘49 please let me know ! Thank you

That has the potential to be really cool.
Take your time and do it right.
