I'm considering a rack and pinion for my 68 Charger B-body Big block.
please post info on various types. installation issues. and you opinion on this project.
also can I remove existing steering power steering box w/headers mounted to motor.

Check out Reilly Motor Sports set up.

I installed an alterktion in my 70 GTX and it was a piece of cake. I am not done with the build yet so I cannot say how it handles but I am positive it is going to be awesome! All the guys with them in A Bodies rave about it.

What will you do in the rear? Here is what I did, also purchased from RMS

Unless you are considering swapping out the entire front suspension for something specifically designed to work with a rack, I'd advise against a simple R&P conversion and install a Borgeson steering box instead. It bolts in easier, doesn't loose turning radius, avoids adding bump steer, is smaller and lighter than the original box, and its feel is probably as close to a R&P as you can get with a steering box.

Slightly OT, at the PRI show I saw my first "herringbone" R&P, for those that have everything

X2 for the Borgeson steering box. Bolts right in and gives you that "feel"

The reduced turning radius and bump steer issues alone should be carefully considered. The new borg box offers precision and feel that was never available in the past.
