Like the shade tree way he "converted" it to front steer. Wrong way to do it.
I have a 65 Cuda as well and have looked into this idea myself. Nothing firm but an idea or two is popping about my melon like popcorn in a microwave, lol.
No one said you had to do it the Shade tree way they did.. It was just some info,that might be of some help..

The biggest issue with converting to a rack is that it is almost impossible to get a rack the right width to keep you out of bump steer, especially when you try to convert to front steer. There's many ways to get a rack in there, but only so many of them work without killing you.
Wouldn't the "right width" be a rack with the inner tie rod ends at the same width as the stock center link ?
Front or rear steer - the bump steer would just be in a different direction, right ?
Looking for answers here 'cause I've been contemplating a b-body conversion without springing for one of the overpriced tubular front end kits.
When people build hot rods, how do they get all the geometry right - or don't they ?!?!?

After a little more research I found this: http://www.longacreracing.com/articles/art.asp?ARTID=13Seems the only issues with a conversion would be; a) find a rack with inner tie rod mounting points the same width (or very close) as stock (measure the stock center link holes) b) get the mounting height right In fact, doing a conversion to a front steer rack in a Mopar might actually improve bump steer because (if I've interpreted the article correctly) the torsion bars would have been in the way and preventing the inner tie rod ends from being in a direct line with the lower control arm pivot point. Yes, no ???

If you can find the rack with the right dimensions, perhaps do something like this... I did the conversion in my old Aussie Charger years ago with a K frame from Oz, it is a very common swap that has been around for over 15 years now.  The rack swap and 5 speed swap were a couple of the best things I did to the car. I will have a rack in any Oz Mopar I end up with again for sure. The rack used is a 14:1 ratio by the way and no bump steer issues, etc.

You also wouldn't want to use the AlterK in really anything other then a race car.
You know I have looked up most of your post but I can't find anything were you actually state why you have such a hate on for the AlterK  .
So what's wrong with it?
The way the unit is designed, the energy of the front suspension is transmitted directly into the front framerails. Those front frame rails are not built to take that kind of stress without strengthening. Without strengthening them, they can fail. No one has reported any yet, but it can happen.

Loose weight, and alot better steering feel with the rack versus the box and assorted related steering linkage in my case. (You also gain header clearance on a RHD when you loose the frame mounted steering box..for the V-8's at least..no different for the Hemi cars  )

The Alterkation dosent put all the force on the frame rail.Look at the setup.The mounts take it all that are built in.Bill has been selling that setup for years and no problems.Go to BBD and look at some of the people racing and street driving them.One guy has like 7 years on his and no problems.Rocky

This is true for a rear steer setup, not front steer. For front steer the rack will need to be wider by twice the difference between the outer tie rod width and the lower ball joint width. This is to get the Ackerman right (or close). Then your problem is getting the tie rods around the strut rods.Quote:

They don't always get it right.

I've gone over the design many times. It puts all the stress where it was never meant to go. You can go look at the picture on the RMS website and see where it bolts to on a vehicle very easily.
