Step 1) Panhard Rod. This will keep the body centered over the rear axle.
Step 2) Get rid of the cut down leaf springs. Look under the rear axle spring perch and you’ll probably find they are already broken.
Step 3) Replace the springs with adjustable trailing arms. You can build mounting plates and use the existing mounting points used by the leaf springs.
Step 4) Install a pair of coil overs on the back. For an upper mount you can easily slide square stock across the top of the rear framework by the fuel tank. I currently run 500# springs on each corner.
What are you running for a rear? The Pinto rear can’t take a built 2.3 let alone a 5.0..
