67 Fastback PS to MS

Hi Guys,

I just had a quick question, do I really need to replace the Pitman Arm (PS) with the MS Pitman Arm? Are that different in design? The PS Pitman Arm is still good as new (replaced it a coupe of months back). ANy insights would be greatly appreciated. BTW the car is a 1967 Fastback with PS.

Thanks Guys,

PS to MS

Thanks Stanger, your advice is much appreciated. Now I have to go buy one.
