Sometimes these steering arms are included with a "kit". Sometimes they are offered separately. Other kits don't include them or even tell you that you might need them. Because they are typically a billet piece, they aren't cheap and they do add significantly to the cost.
Also you need to pay attention to whether your dropped spindles (if you have them) have full turning radius capability. Also some dropped spindles have a built in steering arm that can't be replaced or shortened (that's rare).
Any rack and pinion conversion is going to be more expensive and more trouble than a power steering box. At the very least, it's often hard to run the steering shaft around/through most of the headers on the market. People get fooled thinking R&P makes clearances to the exhaust easier because the box is gone.
