The box in my 88 bird is shot so i figure ill put a better ratio in it.
My question is what year and model should i order for?

I know some g bodys came with them like the f41

Thanks for the help!

 

F41 = hd suspension - upgraded shocks, upgraded springs, boxed rear control arms, rear stabilizer bar, heavier front stabilizer bar. I know because my 72 buick gs had it.

 

WS6 trans ams have a 12:1 steering box. Some other cars too but it doesn't really matter because you just need to look up any of those cars for the part number.

The aftermarket rebuilders have completely lost track of what parts belong to what and they just build mystery steering boxes now.

If you really want to know what you got then try to find one in a junkyard and then have that particular box rebuilt and returned to you. I'll just tell you right now though it is expensive!

 

Turn One Steering. Be prepared to pay. They'll build you exactly the box you want and pair it with a pump and cooler that can deal with whatever size tire you throw at it.

You'll end up happier despite the increased cost over a "rare" used, and possibly worn out "unicorn" steering box that you might have to get rebuilt anyways.
