For this Pontiac kit we used a front steer, center take-off style rack and pinion made to match the original center-link of these cars. The rack and pinion match the stock front suspension for great handling, responsiveness, and no bump steer! The rack comes mounted to a one piece bracket which bolts up to the same factory holes on the frame that held the steering box and idler arm.
We did our first install on a 455, and we used Dynomax Headers (Their Part #86104). Other headers may work, but might require modifications.
