If you are going to be welding them in why not just buy some raw materials. Some 2x4 steel tube and modify it as you need to. Maybe Im missing the "weld in" part. Just welded into the front and rear but not the floor?? I have 2x4 steel connectors that sit above the rockers but I had to notch out the entire floor (actually made a new floor pan) to fully weld them into the floor. So is that it? They are welded into the front and rear while not having to modify the floor? If so I gotcha
