As far as fast ratio goes, options are pretty limited to manual boxes with a 16:1 ratio (if you can find one). On the power boxes, I think there is only one ratio offered. You can use the longer idler and pitman arms from Firm Feel to speed the steering up a little. You can get the standard chrysler "overassisted" feeling dialed out with the firm feel P/S box. Flaming River makes an updated (cast iron) manual box. It would be cool if you could swap out boxes like on GM cars. I'd love to have one of those cool variable ratio 80's/90's F body setups.
