Steering

I put factory power steering in my 67 with a lil 14 inch steering wheel. Love it. Sure there's a little looseness in it ( which was amplified by the OEM steering wheel diameter ). OEM gearbox steering never did feel like the rack and pinion steering we're all use to today. You would need aftermarket to get close to that.
Optimal route would be finding a owner willing to trade power for manual, the column shaft with box coupling, crank pulley, everything.
