I would recommend the steering gearbox it’s not a simple drop in but it’s worth the work anybody that modifies cars knows that you run into issues adding 3° positive caster does wonders for the way the car drives I’m quite happy with mine Note I’ve been doing alignment and mechanical work for the past 50 years

I put this box in my 1955 chevy show car it took me 4 hrs to install with help from another person. after test drive the steering will not return by it self when turning left or right you have to steer it back yourself I should have ponied up the money for rack & pinion system. thats what you get for going the cheep way out.thinking about removing the box and returning it.
