Pitman arm differences - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Can anyone tell me the dimensional differences between the '68-'72 and '73-'82 power steering pitman arms? Is the drop different, the length, or pitman shaft hole?

Thanks.

I think they changed in 71, if I remember right they are the same from 71 to 80 something.

i used a 82 1/2 power steering box and pitman arm on my 72 1-ton.bolted in and works great.

the main difference that i am told is that the 69-72 ps boxes are standard and the 73?-87 ones are metric. i'm not sure if the pitman arms conform to that as well but it may.
