Hi guys! How can i check what Steering gear box is build in my 66 f85. The box is mounted on 4 bolts - There are 4 bolts but it is only mounted on 3 bolts, the 4th is "hanging"!!!!

Newbie Info please: The difference between 10:1 and 14:1 is the amount of power I need to steer or the steering react faster??

Thank you

 

The Saginaw steering box has four threaded mounting ears because that same box casting was used in HUNDREDS of different models, including many non-GM cars. Only three of the four ears are typically used for any specific application. This is normal.

The quicker ratio will be harder to steer. For a power steering box, this is less of a concern.

 

Thank you. So its Not worth it to change it?

 

That's up to you. Most people prefer the quick ratio for better handling.

 

hey joe what boxes trans ams and years plus monte carlo ss,s and years interchange. thank you jfb. 65-72.

 

All of them. The G-body boxes need the adapters for the metric fittings and I think you need a conversion rag joint (both are readily available). The second gen Trans Am with WS6 box is the preferred one, but the internal stops are wrong for an A-body - you'll get a different turn radius one way than the other way. Power Steering Services basically puts the WS6 gears in the A-body box to build their quick ratio boxes.

 

I just put a 93-98 Jeep Grand Cherokee box in my 70 Cutlass. It is a 12.7 : 1 close ratio, same ratio as the Camaro box. 3 turns lock to lock the Camaro is 2.5 turns because you lose some of your turning radius . It's the Saginaw box with the biggest factory torsion bar and the stops in the right spot to get the full turning radius. Plus they are easy to find. $40 at the pick n pull. I needed to order some bubble flare adapters and install tool for $20 shipped from Lee's engineering to use my factory hoses. I also had to get the Lares 200 steering coupler from Rockauto for $25 shipped. I used my A-body pitman arm so I needed to barrow a pitman arm pulled from Autozone. The bigger torsion bar makes the car feel and drive like a newer car. For the price it was cheaper and easier then rebuilding or replacing my leaky factory box plus it's a price nice upgrade too.
