Pitman Arm ID
I need a drop pitman arm for my 67 F100 4x4. Currently has a Bendix P/S system, which I've learned was swapped in. The pitman arm that was on the steering box is stamped CT7A-3590-AA. Can anyone tell me which vehicle(s) that could have originally been installed on? I assume that if I can figure that out I'll be able to find a drop pitman for that model and be all set to go.

That is the stock steering arm for a 67-69 F-100 4x4 as shown here:
Section 35 - '64-'72 Ford Trucks Master Parts Catalog - FORDification.com
Try Torque King, Jeff's Bronco Graveyard etc for one.
Google with the Id number.
Seems to also have been used on 73-75 F-100 4x4's if I read this right:

If that's the case then pretty much any pitman arm for a Ford of that vintage will fit the sector shaft. The tapered holes for the draglink end were different on many of them though.
How much drop are you looking for? The ones we carry for the full-size trucks don't have as much drop built in as do the ones for the Bronco (https://www.wildhorses4x4.com/catego...ord=pitman+arm), but they are beefier and have the larger tapered hole. Where my knowledge fall flat is what size tapered end your draglink has.
You can see in the pics that the smaller arms have a more distinct drop, whereas the '78/'79 arm is only about 2" or so from stock. But that's the most common from the old days. Not sure if there are others out there now making F100 arms, but there might be.
If you're lifting it more than 2 or 3 inches, you may want custom stuff.
Are you also going to be dropping the upper trackbar mount?
Generally speaking the trackbar and draglink should be the same angle (parallel) the same length (roughly) and as shallow an angle as you can achieve.
Which means that you usually need a trackbar drop, or riser bracket to keep the bars as close to parallel as you can.
If you're going more than 3" of lift, you might consider other customizations.

I remember back in the day a few guys who needed to rework the pitmen arm would visit a loco spring shop that heated it up and bent it x mount then dropped it into a barrel of oil till cool. No one ever had any problem with it that I ever heard of..
But a person should always start turning the steering wheel once you vehicle wheels start rolling to put less stress on the steering box & tie rod ends..
