i have a 1965 f100 2wd and have read a few forums on this conversion, i got a power steering gear box from a 1975 f150 2wd, and i have a pump on the front of my motor from i believe a 1992 mustang, i have mounted the gear box and shortened my steering column, however i have just come across the fact that the shaft for the pitman arm is larger on this new gear box and the pitman arm for the 75 has a ball joint where the arm from the 65 does not, does anybody know what arm i need to get? i am hoping there's a car out there with the same size output shaft on the pitman arm and no ball joint on the other end so that i can use it on my 65 tie rods. any help is greatly appreciated thank you
