why are pitman arms different

[barryv]

hi, i have a 72 cuda with powersteering.i want to change my pitman arm,but i notice the arm for 70-72  is more money than 73-74.can either one be used.i am assuming there must be a difference since prices are much lower for newer years,thanks

The differences on why the 70-72 pitman arms vs. 73 and up is that the spline dia. where it connects to the PS Box is smaller on the 70-72's. There were more made of the 73's up. This may be the reason why the later ones cost less. Rick Ehrenberg sells the Pitman arms at a good cost on E bay. I haven't seen anyone at a better price.

He sells both types. Make an offer to him. He's flexible on prices.

thereis another difference , the pitman arm sits above the center link & the tapered shaft drops through the center link  down on the early pitman arms , the later pitmans the arm is much longer & drops below the center link with the tapered shaft point up through the center link , the tapered hole in the center link reverses

Where are you getting that information?  My 73 Challengers pit arm drops down into the center link as does this 74 Cuda.
