I don't see how you can use this to remove the center link from the pitman arm and idler arm:
That is more appropriate for a tie rod end. The center link extends to the left and right so the arms on that tool are going to get in the way.
This tool (mentioned above):
Does have the correct geometry for the pitman and idler, I don't see many vendors selling it on amazon, one that does has 6 different sizes for sale, but these are advertised as bearing pullers. ?
Amazon mostly sells these tools as kits, like this one:
I have something like the tool in the upper left corner, I bought it to pull the pitman arm off the steering gear of my '01 Ram (FWD) but it did not work - it was deforming (I was using a really long bar). I think the socket was also deforming. In the end I took an angle grinder to the arm, one-handed using my left arm on my back under the truck, and made a diagonal cut through the pitman without touching the steering gear shaft, and then the arm pulled off easily.
As I take apart a front sub frame I recently acquired, the arms of that tool in the upper left corner are too thick to get into position to remove the center link from the pitman arm, and the gap between the arms are too wide for the idler arm. A better candidate for the idler arm would be the center tool on the top row. The tool on the top right would be a better candidate to remove the center link from the pitman arm, but Amazon doesn't sell it by itself, only in kits. Ebay does sell it separately.
I'm not sure about the strength of the tool design of the tool in the center-lower row. I just don't see a tool of that design holding up without bending/breaking.
So that's where I am right now, looking for a tool to remove the center link from the idler arm and pitman arm. I could just remove the pitman arm and idler arm from the frame but I wanted to take all these components apart and separate them for storage / possible future use.
