'30cpe- nissan rack and pinion, bump steer

I bought a 30 model coupe that has a nissan rack and pinon/straight axel, it has horrible bump steer, I was trying to consider the best way to correct, be it move the rack to the axel and let it follow, or change over to the vega cross steer version.
I didnt see any thing in the archives to address this prob.

Rack & pinion steering will only work correctly on a straight axle if it is attached to the axle. If you have the present rack & pinion attached to the frame this is why you have serious bump steer.

That being said, there is a new rack & pinion unit available that bolts to the frame the same as the Vega steering box. It should work very well and the cost is similar to a Vega box. One further note. If you go to cross steering, whether a Vega box or the new rack & pinion, you will need to add a panhard bar from the left side of the frame (drivers side) to the right side of the straight axle (passenger side). This is a very important step that should not be overlooked.

I did forget to mention, that I have a panhard bar mounted, I have heard some talk about this new style rack, but no mention of where to get it, or who makes it.
I know that having the rack on the frame is not good.

I don't have time to do a search this morning but a couple of days ago someone here posted that they had just completed the installation of that new rack & pinion. They were very pleased and listed a link as well. Search the last three days or so of posts.

I found it. Go to this post:

rack&pinion?

I've installed both the rack and pinion, as well as the Vega. On the straight axle autos, and I find that the easiest and best by far is the Vega. In order to remove the "bump steer" from a rack.. is to mount it on the axle. Then you need to fabricate a steering shaft which will "telescope" as the axle moves up and down.The Vega installs easily on the A and lines up pretty well with the steering column. Keeping the need for u-joints down to a minimum.
