I have a, what i call dumb question, the rack and pinion valves went bad on my bird and i have another out of a cougar but i think its not to far off from the one i replaced it with, so my question was would a rack n' pinion set for a 79-93 'stang fit a 87 Tbird or is the stangs smaller?
I used a 87ish mustang rack on my 87 tbird. All of the fittings were the same size. I even used the tie rod ends.
The rack is the same , there is a difference in ratio for the performance and non performance racks and each has a specific pump .
Although some people have not had any problems mixing the parts, why worry. New pumps aren't all that much, and then you have a new pump, too. :)
I converted mine to an aftermarket manual rack but the spline is different, so you also have to replace your steering shaft. Why did Ford use two different splines? Why do they not offer aftermarket racks that are a bolt in with the larger spline?
