This packet is about setting up your rear suspension. The references to the rear axle are for an 8” Ford out of a Maverick. If you are using something else, you might have to make some adjustments to the given measurements and brackets.
Disassemble the housing. Be sure to keep track of the nuts from the third member drop out and the axle flanges as they are costly to replace. Clean the housing inside and out. Remove the old spring perch pads. You can grind the areas where you will be welding, but I sandblast the outside of the housing. This gives you a clean surface to insure good, sound welds.
Measure the axle tubes, they do vary even one from th same manufacture. Fab the hairpin housing and frame mounts and the upper and lower coil-over mounts. You will find it much easier to measure and locate the rear axle if you make up a set of solid struts to use in place of the coil-overs themselves. It will also keep them fresh for your final assembly.
