Subframe Connectors For Strength
Classic Mustangs suffer from inadequate structural support; they twist and flex under harsh driving conditions. When chosen and installed properly, subframe connectors stiffen the underbody and provide exceptional support. Not all subframe connectors are created equal. Heidt's has designed one that follows the floorpan and doesn't require welding. It's a removable, bolt-on design, however, we suggest welding it for optimum strength.

Heidt's subframe connectors are easy to install and remove. If you desire, they can be permanently welded.

Once the spacer and subframe are in place, install this spacer and bolt as shown on both sides. The bottom bolt holes are for lower links.

Subframe connectors dovetail into front framerail extensions as shown. As with the rear brackets, center-punch each hole; then drill a 1/4-inch pilot hole. Drill four 1/2-inch bolt holes across each framerail extension.

It's a matter of personal preference where you locate link adjustments. Heidt's suggests at the axle for easy access.

Stang-Aholics had a custom Currie 9-inch rearend built for this Mustang. It has been powdercoated black for looks and protection. Currie welded the Heidt's brackets in a jig.

All that's left is the Panhard bar, which maintains axle stability when things get wild. Once installation is complete, we suggest a precision four-wheel alignment.
