Let's see... 59 should have independent front suspension, right? The thing to look for is location of the rack next. Where is your drag link, in front of or behind the crossmember? Wherever it is, that's where you want your rack. Most front drive cars have racks behind the crossmember, rear drive in front. If in front I'd use a T-bird power rack (or Mustang, Aerostar -- all the same), if behind I'd go with a Ford Taurus rack or from some GM application. The Ford racks work great with a GM power steering pump.
The next problem will be turning radius. You'll lose a lot because of the length of the steering arms on the knuckles. Most R&P arms are only 5" center of ball joint to center of tie rod end. Stnadard steering box arms are usally longer -- mine are 7" from center of ball joint to center of tie rod end. Luckily my Rambler has separate steering arms so I can make new ones. GM arms are typically cast as part of the steering knuckle, so have to be bent or cut and welded.
The Ford inner tie rod end is also the rod itself. You can trim them if necessary to make shorter. Buy different tie rod ends to make longer. Mustang II and Escort (the boxy Ford made one) use a short tie rod end, Tempo and late Mustangs use one about an inch longer, and the T-bird uses one about an inch longer than the Tempo end. One should work for you.
