Hello All

My steering box is shot. In looking for a replacement, I found out they offer 2 different ones. (different number of teeth on gear).

Does anyone know the correct steering box for my car??

Thx

I would think your original is rebuildable.

There was one ratio when new. They have offered a fast ratio now. Do you have power or manual steering? I like the fast ratio with power steering. It might be a liitle hard with manual steering.

The ratios were different between power steering and standard. If the pitman arm is still attached to the steering box...we can identify it that way. There are not any visual differences that I know of. Post the casting number off the pitman arm and I will identify it for you.

Thanks for the info guys, but I understand the difference in the 2 power steering boxes is in the number of splines on the box itself to match the pitman arm. 3/4" shaft with 30 splines and 13/16" shaft with 36 splines. In any case, I'll make sure its the correct one. The ratio is 16:1 and 4 turns lock to lock on both. I didnt think it was this confussing.
