I'd like to know more about it too. My 08 HHR has electric assist power steering. Its really seamless how it works. The tightness and lightness of a manual box, no pump, no lines. Would want to adapt this to a stock 67 column though.
But I also found the wiring harness and the elc steering assists for a few hundred bucks. Anyone of us could build this kit for under $300
This is the route I think I'll be taking..
( I know it's Fleebay) But... Chevrolet Equinox - Saturn Vue Electronic Power Steering Controller KIT box epas | eBay
And the steering assists can be found for under $160 all day long..
