Floor Support Replacement Advice


Recommended Posts

Hey Guys,


I'm planning on replacing the driverside floor support on my 73'. Has anyone done this before, or know of a good build forum involving this?


I need to cut open the bottom of the torque box in order to get out those spot welds holding it onto the frame, but if I do cut the torque box open am I good to just weld it back up or has it lost it's purpose once you start cutting into it?


Anyone have any experience with this, thanks.

Before you cut too much out make sure the body is supported and kept in correct position. If you flex the body and weld in a new frame rail nothing will align properly. If your floor was rusty good bet the cowl is leaking letting the water get to the floor so check that also.

When a man is in the woods and talks and no women are there is he still wrong??:P

By the looks of the pics, its not in that bad of shape. Doesn't look like there are any holes and the metal is still pretty thick. I would clean that area up. Hammer back the bent areas and throw a few welds on those seams. Use some por15 or eastwood frame paint in there and move onto the floor pans.
