If you plan to use a Ford 8.8 rear end or a GM rear end with the upper bar ears on the center section, we have a kit with brackets to fit on the upper axle bushings. These brackets must be welded to the upper bars after the bars have been cut to length. The upper bars in the kit are longer so the kit will work in frames of different widths. In both the welded and ready to weld kits, these upper rear end mounts are not welded to the bars. Because this bracket has many applications, the 7/16″ diameter bolt hole must be drilled to your bolt size.
GM has used a triangulated rear four link in many of their cars for decades. The design eliminates the Panhard bar. To accommodate many frame widths, the formed upper frame brackets may need to be trimmed. Bars are 1″ heavy-wall seamless tubing, tapped one end 3/4-16 and notched for the urethane bushing tube on the other end. Coil-overs can be mounted in one of three holes.
