Borgeson steering chuck....reports on steering feel versus stock P/S.

There is still that dead area where the steering wheel moves before the linkage and tires do.

What do you have for a coupler between the box and column? I have a Firm Feel 3 and Flaming River u-joint (and Column with slider) and no slop with a 900 psi Saginaw Pump. My dad has a Firm Feel 1 and stock Saginaw pump on a 66 Coronet and he had the center play slop and it turns out his stock coupler, even though he rebuilt it with new shoes, still had slop. He shimmed it until it was gone but could still slide.
