Re: ISO steering box sources
For a rebuilt box, I'd recommend doing it local. Rebuilt steering gears are hit and miss in my experience.
I went through three and finally got one that wouldn't hunt. The good one lasted 1 year 2months.
I finally bought a new one.
A friend with a 66 chevelle went through two rebuilt boxes and finally got a new one.
I'm in the process of replacing the box in my 69 chevelle, and it will get a new one.
