I searched but did not find.

What are the actual differences between a power and manual steering pitman arm?

Is it a length thing, or are the centerlink/box connections different?

it's not a length issue they are the same. the hole that mates to the steering box is different. the manual box arm has a small hole and the power steering arm hole is large. there are also different p/s arms for different years. 68-72 use the same one. 65-67 a different. 64 could be either. i have either if you need. just email me. tom

Hello, it's similiar to the rag joint; power is bigger on the shaft. bodda bing
