The entire front suspension from a 67 to 72 Chevy/GMC pick-up unbolts with the cross member it is easily adapted to fit most any other truck frame rails. The nice thing about it is that all the suspensions mounting points are part of the cross member and if you need a narrower track width you simply narrow the cross member. The motor mounts bolt to both the frame rail and the cross member so if a V-8 swap is in the works they are easy to adapt to fit after the cross members width has been altered. This also give you a choice of weight ratings from ½ ton to 1 ton duelie as they all come apart in the same component type manner, much like the aftermarket front ends sold by the rod shops
If you wish for a more car like ride many prefer to graft a Nova/Camaro front sub frame to their trucks.
