you do not need the upper bar if the springs are used.but if your using the bags? if yes to the bags then i would use a real four link and you would need a track bar .pan hard .or watts . less you triangulate the bars like Gm car or ford did it. then a track bar is not needed. if you use the stock springs and use a four link .or ladder bar then you should float the rear axle .all points for bars are base off the crank center line were i am from .more or less whats in the photo is a 1/2 ass ladder bar set up . the raise and fall of the rear axle is some what linear as if you hit a pot hole it will not move one side but the complete axle where there is some bind and good strong mount points are needed to deal with that..... but its not bad but not the best for ride were a 4 link may ride abit better but with a solid back axle its only going to get so good. i built them both ways with ladder and four links .my chevy is about the same set up as any car leaf spring car.i have floater i made many years ago moved the springs under the frame and used comp ladder bar s i had the car stock and the way it is now the ride is not that bad as some would think still better then many hot rods when you float the spring s you should use a track link bar of some kind to keep the rear axle from moving side to side as you do not clamp on to the spring over the center bolts with u bolts to hold the axle to the spring so you can get some side to side movement. SO why they have it set up like this in photo ? they do is for the bags as the upper bar having its owne mounting point will bind for the lower ride deal .i built mine for alot of power only...getting the spring eyes getting pulled out and spring whined up. pinion climb can be a very bad thing
