I am needing to see if a crossmember I made will clear once a bed brace is removed.

Can someone please measure the gap between the top of the frame rails, and the bottom of the bed floor (with cross brace, and without)? I would need this measurement above the axle. I want to know if a 1-1/2" square tube sitting on top of the frame rails will clear under the bed floor.

Thanks in advance for your help.
