If going from one unknown to another unknown, it's simply best to mark the dipstick or adjust the tube length during an oil change.
A truck tube and dipstick is available new but for '57-'64 alone, there are 3 or 4 different ones listed in the MPC. I'm sure '54 to '56 adds more. And that's only for trucks. How you know what is currently installed or what will be needed, I don't know.
