Where can I get one? The spohn manual rack is 3.75 turn to turn which is too much. I am looking for something with a quicker steering ratio.

you have to realize two things:
a) this is a manual rack, ie, no power steering. anything less will really wear you out.
b) rack and pinions are measured differently... the lock to lock only crudely estimates the actual ratio, which is really determined by the pinion size
another thing to keep in mind is that to properly use rack and pinion you will need to shorten your spindles, which will effectively increase the rate of steering.
you can shorten the spindles even more and have a much higher rate.
IMO steering systems should be measured in degrees of steering wheel input per degree of wheel turn...
the lock to lock thing is really outdated.
for example
box a from an s-10 is a 2.75 LTL box
box b from a camaro is 2.6 turns LTL.
immediately the camaro one looks like a faster ratio, but upon closer inspection, you find that the s-10 box has a greater throw or angle at max lock than the camaro one, so although you turn the wheel more to get to full lock, you get more steering angle in the end.
the truth is that these two boxes are both 12.5:1 or whatever the ratio is. the point is that the ratio is the same and you cannot use turns-to-lock to accurately describe a steering box
Less turns from lock to lock also means you need more mechanical leverage to turn the wheel. Without using a power assist, this increased leverage is achieved by using a larger diameter steering wheel.
If you want a quick ratio steering, stick to a power assist. You won't like a quick ratio manual steering.

You can use Racecrafts drop spindles with modified steering arms to help get back the steering radius. I ordered a set. We'll see in a few weeks once things start coming together.
