Quick Steering box ID

While there may have been a different color paint daub from the factory indicating the 16:1 boxes from the std manual 24:1's I've never personally seen it or any other identifier. The only way I can tell is to simply turn the box and count the revolutions. The only years I've ever seen it listed on the order form were 65 and 66, and only then as an upgrade to the Formula "S" package. In the seventies and eighties Mopar Performance offered a 20:1 worm and sector kit as a "quick ratio" upgrade but never the 16:1 ratio. The 20:1 ratio is what either Firm Feel and/or Flaming River now offer. Neither offers the 16:1 ratio. Prior respondant was correct about the T/A challengers and AAR cuda's using a different pitman arm to simulate a 20:1 ratio while using a 24:1 steering box. This "E" body pitman would likely fit late model "A" body manual steering boxes but would likely alter steering geometry so much as to make the car useless for anything other than idling to cruise spot and back (can't say for sure however since I've never done a geometry study on this swap). Also, the early 16:1 ratio sectors used the smaller diameter pitman used from 60-66 typically. So if you mounted one in your later "A" body you would still have pitman/steering issues to deal with. Best advice- accept that 20:1 is "quick" enough and buy the new aftermarket stuff at whatever the current price is. It's truly bolt in and go.
