Hey guys, thanks. Right now the passenger side torque box is in and the driver side isn't. I would think that would be fine cause 67 only had one in the body.

 

i think gypsyr is right, you should be ok. my suggestion would be though to hang the doors, and get the door gaps as close to right as possible, then weld in some bracing to prevent the body from sagging before you install the floor pans, just as an added safety precaution. that way when the new floor pans go in, they will be as close to perfect as possible and you wont have to fight the door gaps later on.

 

Without seeing pictures it sounds like it will be OK to me. Most of the lower structural support is actually centered around the rockers and torque boxes.
