Rack and pinion steering.

Something else tht might help you out. This guy's selling a 1972 Dodge Dart with a rack & Pinion already installed. If he did it, you might get the info you need;
1972 Dodge Dart
that's just mustang 2 junk up front with, likely, a universal x-member on some 2x3 frame

same thing can be done, and better with RMS, hemi denny or hitting up speedway, loading a cart and melting a credit card.
