So I did this about a year ago, maybe 2.

Everyone here recommended firm feel or steer and gear, with a couple of exceptions.

As mentioned above Lares remans were also recommended.
I found advanced auto had online discounts and ship to store for free.

I decided to order a 74 and up box so I could use the cheaper pitman arm as well.

while it still has some play in it, the old one was much worse.
But the alignment guy still never quite got the steering wheel straight.

Calling lares they said I had to have the car running, and even with that, the slop has me steering slight the off center. not holding like it drifts, just that the alignment shop couldn't get any closer.

before I would say something like 70 to 80 degrees before the steering "Caught" and the car would turn.
now it is more like 10-25 degrees.

I would say a hand in either direction before it catches.

A few detractors of firm feel and steer and gear pointed out I might get the same thing from them, AND be on the hook for shipping if I wanted it fixed.

the price at the time was like 150 for the lares through advanced auto.
so it was a no brainer cost wise.

I see now they don't offer that box anymore.

rock auto does and it is around 250 with 100 dollar core.

FF is close to 400 with 250 core charge.

steer and gear is 320 plus 195 core

and you are paying for shipping back for both, not sure about shipping to you.
