M Code 351C originally. Basically a road race car that is street legal.
Round tubing is more resistant to torsional twisting then box. Think of your driveshaft. You could do it the other way if you chose to. It is the floor you are talking about. If later on you need to replace the floor there is that much more to monkey with. There are plenty of people making these so you have lots of choices. BTW the floor really doesn't gain you anything, if you are twisting it up, you are bucking your floor and stressing your seat mounts. My seat mounts weighed at good 20lbs each it seemed when I took them out. I put the big girl on a diet too when I did mine. Of course mine is mostly race car now while still street legal.
