I would think you would want to attach a panhard bar to the carrier housing bolts. A simple 1/4" flat stock with an ear added to make the bar attaching point double shear, attached to three of the center section mounting bolts (you can shift towards either side for more offset, if you want) will be strong enough unless you really getting carried away. Keep the bar connection point as close to the top of the center section as possible, excessive height would not be your friend. Least that was what we did when we were dirt track racing. Gene
