Factory is 4 turns lock to lock, the only faster ratio box would be a
SPA-T box from a Boss Mustang. It has 3 turns lock to lock and is variable ratio. It is a saginaw gear that you need to make custom lines if you have the Ford box right now. It is a direct bolt in gear though.
Oh, good luck finding one though, I have a '73 Montego I need one for.
4 turns lock to lock kinda' sucks especially parking this "land yacht".
The Ford bolt pattern Saginaw three bolt steering box mentioned previously in this thread is not the end of the line here. There are several companies that take these boxes and replace the internals with Trans Am / Z-28 parts. The result is a 12.7:1 ratio, which is much better than the 3 turn lock to lock Ford version.
I spoke to Gail, at Lee Manufacturing and she gave me all the details. They sell the steering box outright with no core or exchange for $440.00 and they recomend that you send them your power steering pump to be recalibrated for an additional $135.00. That includes new seals, and fittings, but any other parts are extra.
There web site listed below is just a home page with an email link so you will have to call them if you want additional information. http://www.leepowersteering.com/
I know it is an expensive upgrade to buy outright, but if you already have the box you could save yourself a bundle and put the TA / Z-28 parts in it yourself.
or you could buy an add on in the shaft steering quickener in many different ratios from Afco,Speedway ,or Peformance bodies etc . They are super easy to install and will put 2 more joints in the shaft to better collapse the sector in the event of an accident
Cool, if you have time I'd love to see a thread detailing the conversion (although grafting a section of another frame is a bit scary). Do you think you'll be saving significant amounts of money over going with a R & P kit?
