Not a smart a$$ remark but the floor looks very solid so why remove it? If you have access to a plasma cutter it would remove it with way less damage than breaking spot welds. The 90* break at the front is a perfect guide and a straight edge across the back would leave very little clean up. There is also a hump in the floor pan itself which would have to go if a completely flat floor is your goal. Sure hope it's not for bucket seats.Pics are of the floor in a 52 Suburban (same floor as a panel) that was so rusty the riser had to be removed for a replacement floor pan to be welded in. The after pic shows the riser back in and with a new tip on the plasma cutter it's only 1/16" lower than factory. The floor is viewed from the underside but shows the "bump" that is there even if the riser is removed.
