rear suspension was completely shot on my truck,even the spring perches were welded crooked to the frame so decided to order a 4 link kit from welder series, comes completely cut and ready to weld up, all you have to do is weld the bushings to the pipes and adjustable bolts, weld the front bar mounts to the plate provided and your ready to go! i wanted to plate the outside of my frame where the front 4 link mount to,found 2 pieces of scrap angle iron that did the trick and telded th mount to that,leveled off the frame,next i took a plum line and made a line on each side of the frame indicating the center of the rear axle, removed the complete rear end,springs and perches,lifted the new rear end in place and centered it side to side and ligned it up with the centerline,tacked it on each side to the frame, assembled my 4 link, clamped it down to the frame and leveled the rear end bracket, tacked it to the rear end and the frame, removed the links, took out one of the rubbers and put back the spacers into the rear end mounts and finished welding, as for the panhard bar had it in but didn`t like it so i will be putting a parallel panhard bar later.
