im in the process of converting from power to manual on my 69 chevelle. I just bought a (A-body steering box)5679142 and pitman arm 56792071. Do i have to change the center link?

You should have it all ... I don't believe you'll have to change the center link.

how about the rag joint? mike

the steering box does not have the coupler attached... im in the process of getting one..
how do i get the coupler aligned properly?
