use the same cylinders and coils if you want. sperate everything. your axle housing will have some sort of spring perch or tabs welded to it.You need to take them off and have either a flat or no platform on the housing.I suggest powerballs, so You find the angle you need them to be welded on (the angle the stock springs would be) and weld them on. then you need a pair of dougnuts and a pair of reverse cups.Get reverse DEEP cups to save coil(go lower) the end of the cylinder piston screws onto thepowerball, and the rever deep cup sits on the coller on the cylinder casing.the coil sit on top of the reverse cup and just since you already have the doughnuts, they sit on top of the coil between the spring and the frame coil perch. So all you really need is the cylindeer mounting (powerball) and reverse cups
