Racing Seat Installation

I am thinking of getting these seats to replace my stockers since my drivers seat is bending outwards . I was thinking of getting these seats since they still have the leather look, and come in tan to match my interior. Problem though, is how can I successfully mount these in? I was thinking of getting some Corbeau seat mounts and welding them on, but is there another way? Can the stock mounts be used somehow without welding?

Typically racing seats same some weight; the stock seats are on the heavy side.
