Subframe Connectors by Competition Engineering

If you just bolt them in , get some 2 inch spacers into the frame so you can tighten the bolts without crushing the frame rails , like the trans cross member bolts. A good hardware store has them or cut your own from thick wall 1 inch tubing. There are drain holes in the frame rails , and use a flexible magnet to fit them into place. May have to open up drain holes some with dye grinder.
