We have a different connector for the Long Wheelbase cars
CNC Machine cut from 12ga steel (original factory rails are made from 16 gauge material) and CNC bent for a precision fit, these frame rail connectors are designed to be welded in to your existing unibody floor pan. No cutting of the floorpan is required and once welded in, they create a fully boxed frame rail connector that is stronger than the original factory frame rails!!
