I replaced the floor supports and partial toe boards in preparation for full floor pan replacement. I clamped the floor supports to the frame rails on the sides and one clamp inside the frame rails. Welded them up. Fit amd welded in the toe board patches. The car is supported under the rockers, the front is on the front portion of a rotiisere, everything is level and the rear axle and drive train is removed. I was going to weld in the inner portion of the front torque boxes and then move on to the floor pan removal. I had cut out the front portion of the floor pan to access the front floor supports. the right side is level with the floor pan marks I made and the left side is about 3/8 to 1/2 inch high. The car is a 65 fastback. I am stumped on what my next move should be. Any suggestion would be appreciated. A big hammer? Thanks in advance.
