Manual Steering Box Replacement Question
I swapped my 68 Barracuda over to power steering. It has been the single best modification behind disk brakes I have done for my driving enjoyment.
If you go that way you can eliminate the over boosted feel of Mopar power steering from that era by removing the pressure relief valve from the pump and put some spacers between the cap and body to reduce the pressure. I bought a kit from Summit by March that gives you a bunch of spacers of different thicknesses to Taylor the feel to your liking.
