Pitman Arm Compatibility

My own car is a great example. I went from an early small spline power to small spline manual box. I went from a 67 K to a 73 K. so for awhile, I had the early small manual box in the 73 K with the early linkage and 68-72 style idler.

Then I scored a later steering box, this is just how things worked out. so now it will have a late, big spline power box, with late steering link and idler, and 73 / 74 K member is still in the car.

When you get into

box spline size

The year of the K affects front anti-sway bar type

and the type of the anti-sway bar determines what factory lower control arms to use

then you toss in drum or late disk brakes, so now you've added THAT hardware mix.

"for awhile" because of my situation, I had the original 67 drum brakes and 67-72 steering link mated to the 73 K member. In other works the only thing I change temporarily for several months was the K and the idler arm (unique 67 idler)
