At one time I looked into R&P steering. I had several conversations with rod shops in California. There are/was kits available. You don't want a rack made for a small car (too responsive) but rather mid-size (Thunderbird etc,) and up. I had a lot of questions but when I mentioned liability, a rod shop owner told me not to call him back and hung up.
I couldn't get past these two concerns:
1.) These kits use a telescopic shaft that is supposed to move in & out and up & down with the motion of the straight axle. The shaft must be free inside to move at all times. If it jams just a little bit, your steering can be compromised.
2.) Good steering and brakes are a must have. If you alter the original Chevrolet design (especially steering) and are in an accident, your insurance company can refuse coverage. You can be sued. To cover yourself, you need kits that have been proven to work without causing problems. They need to be installed by a professional who is familiar with the kit.
Today most new generation owners want the whole front suspension updated. When someone just needs power steering, they go with "old School" kit with the Saginaw gear box. These reputable kits are still available and will have a new pitman arm to minimize the effect of bumpsteer.
