Standard wagon typically has variable-rate (16:1 at center to 13:1 at full lock left & right), low-effort steering gear. Very little connection between steering wheel and the tire contact patch can be felt--best described as "numb".
9C1 & Impala SS (and Caprice B4U) have linear rate/ratio (12.7:1), with somewhat greater effort, and better "feel" compared to the production wagon gear.
Only concern (for me) is the unknown condition of many take-off steering gears, which I've expressed concern about numerous times in the past. Without knowing the source of a replacement steering gear picked up in a wrecking yard--collision impact point, mileage on the part or vehicle, whether the gear is contaminated (ie. full of water from sitting in a wrecking yard without protection), any indications of leakage, or any other indications of damage, obvious or not, etc--please use great caution.
If you feel capable of inspecting and qualifying a "wrecking yard" replacement steering gear (or have previous experience working on them), that is good. If you don't, seek the assistance of an expert or use the gear as a core for a rebuilt/remanufactured unit.
