I rebuilt the 2-tooth box in my coupe 12.000 miles a go with needle brgs on a good hard sector shaft & also modified hsg for a needle thrust brg to replace brass washer also shortened pitman arm & installed teflon ball seats.It steers like a dream even@60 mph.I tried another A with F-100 steering & it didnt steer any easier except when the car was not moving, and the steering seemed a little slower.
