As far as making a new frame, that's probably going to be more work, but the advantage is that you can position the rails exactly where you want for whatever engine, drivetrain, and suspension systems you want to use. The standard size for most aftermarket truck frames is 2x6 inches. In certain situations 2x4 tubing might work near the ends of the chassis, but 2x3 simply isn't up to snuff.

Of course you want your frame modifications to be completely safe, since any failure of the frame, or the suspension clip you're adding can have severe consequences, and cause the driver to lose control of the vehicle, endangering anybody in harm's way!
