I was at the little local car cruise last night and one guy showed up with a little 32 ford he had fabricated the power steering setup for. He had used the mid 60s Mustang Fairlane/58-64 (?) Chevy control valve/slave cylinder setup. It was an interesting concept and apparently assisted well, however the execution left a bit to be desired (hose routing).

Even with that setup you’d be into for at least $500 in parts, plus a whole lot of fabrication time.
