1972 Competition Suspension Steering
#1
Anybody know if the competition suspension option in 72 (Q code) had a different (variable steering box?) if it did not have power steering? Or was it the same as all the other 72 steering box? I had a 72 Q code with manual steering and now have a 72 302 fastback, with power steering, just do not like the feel of the 302 ratio.

Sounds like a variable box might get me where I want to be anybody have one they would like to part with?

"There are two different steering boxes for 71-73 Mustangs equipped with power steering. One is a fixed ratio and the other is a variable ratio. Variable boxes all have a tag that reads as follows. 71 SPA-T or V, 72 SPA-T or V, 73 SPA-T or V or SPA-AD or AF. You probably want a variable box."

Power steering will never feel like manual steering regardless of the ratio.

With the manual box in the 72 q code it just felt a lot less sloppy...impossible to turn when the car was not rolling, but a lot more fun to drive. I might try the variable box before I give up on the power steering.

Variable ratio is probably what you are looking for. It's designed to turn easily at low speeds (i.e. when parking), and becomes heavier, firmer, stiffer (how ever you want to describe it) at higher rpms to allow you to "feel" the road and make the car more responsive. If you can't find a variable ratio gear box at a reasonable price, you can have your standard power steering gear box converted by companies such as Lees Manufacturing in California, or Red Head in Washington state.

Keep us posted on what you do!

In the for what it's worth catagory, I had a 72 Q code with manual steering. It sucked!

With the Q code and posi, it had a really tight turning radius, but I did go through a lot of rear tires...

Ray, All,

I'm trying to ID my steering box. It has SPA AF on it. I thought this link sent me to a site that listed all the part number break downs but i cant find it anymore. On our site I have seen it as being describe as both a constant and a variable. I was hoping to find a site that tells me exactly what it is. I want to change the gearing but I think it's more to change gearing and to variable.
Thanks,
JIm
