I installed a 1998 Jeep Grand Cherokee steering box in my yellow car re-manufactured by Lares, from Rock Auto, just under 2.5 turns lock to lock.
Just a side note; our old Buick's have those large steering wheels, when I installed the quick ratio box I quickly noticed it's very easy to over steer. Takes some getting used to, at 70 MPH you can sneeze and change lanes.
Having said all that, I absolutely love the improved handling of the tighter steering combined with QA1 coil-overs.
