Hi I want to convert my car from manual to power steering. I want a quick ratio box was looking at the cardone 27-6509 but not to sure if it's gonna work because I'm unsure of spline issues , also rag joint/pitman arm. Looking for advice and suggestions, car used to be a 6 cyl now an 8 cyl. Thanks!

I used a box from a TA. Early 70's vintage I think.

Thanks Michigan Larry I did think of that but hard to find here. That's why I'll be going with a new one.
