Best RACK AND PINION set-up for Early A?

Gerst Suspension is in your neck of the woods, but I don't know if Carl offers an Early A setup. If I were putting one in MY 65 Barracuda, it would be HDK....all the way! @HemiDenny :poke:
Gerst shows one on their website, but when I called to inquire about it, I could sense a "deer in headlights" look through the phone...
