power steering box what one?

[novaracer]

I have a 68 nova that I need to put power steering on. Who should I get the box from and what ratio?
I see that flaming river makes 4 different ratios....
What else will I have to change pitman arm, rag joint and add lines/pump.
What pump should I run I see that some have a variable psi pump that drop psi when spinning faster I may in the future run a hydrabooster so I think I will stay away from that.
thanks

Seems most here like only one box.

The ATS box.

For cheap you can use a 78-81 T/A fast ratio box. It will bolt up no prob.

Does any one have a link to AST?
If any one is running a Faster ratio box how many turns stop to stop?
thanks
