I bought a steering box from from AZ. The first one leaked, so it went back. The second one worked but steered poorly-I took it out so long ago I don't remember the details.

I ended up with one from Steer and Gear. I like it so much I bought another for my GTX.

It's more money than the AZ unit, but the cars are sooo much nicer to drive
