Modern style Pitman Arm?

[jeepguy1948]

I am using the ‘32 style Pitman arm on my Model A (which now has the F-100 box) I need the same spline, same length pitman arm but I need it with the 7 degree tapered hole instead of the affixed ball. I could certainly do it myself if I could get my hands on the proper reamer but I’m guessing A new pitman arm is low enough as to be not worth it to modify the existing one (in large part because I don’t have a reamer). Can somebody help me out with a source for the correct pitman arm? Thanks
