Hi all and Happy Thanksgiving.

I am at the point of buying whatever PS conversion I will end up using. Through hours and hours of reading and research, this is where I am at with no definitive choice. Let me list them with some pros/cons. If money was so much the deciding factor, which would you buy?

1. CPP 500 box and Ididit retrofit column. Pros: Likely the lest expensive when all said and done. Seems to be a lot of people using them but with mixed reviews. Fairly bolt in with minimal problems. Cons: Questionable quality and prone to leaks at the hose connectors. Can cause exhaust manifold/header clearance issues.

2. Borgeson Delphi box and Ididit retrofit column. Pros: Not much more than the CPP option. Reviews seems to indicate better quality. Fairly bolt in with minimal problems. Cons: Have been some reports of leaks or "odd" behavior. Can cause exhaust manifold/header clearance issues.

3. Unisteer Power Rack and Pinion and Ididit retrofit column. Pros: Current model seems to have addresses issues of bump steer and turning radius problems. Possibly more exhaust clearance depending on manifold/header choice. Cons: Expensive. Could have some oil pan clearance issues. Could have intermediate shaft fitment issues.

4. Unisteer Electra-Steer Column Kit (Ididit column included). Pros: Nothing under hood is really modified outside of steering box shaft shortening. Will not change exhaust clearance. No PS pump on engine needed. Cons: Most expensive of group. Could cause some under dash clearance issues depending on what you might put under the dash. Unable to find any reviews for Tri-5 installs, so somewhat unknown as to possible issues. Your stock manual box must be in good shape with no slop.

Really need some thoughts (or other options if there are any that are much different than above). For reference, I am installing a RideTech StreetGRIP suspension and will put new upper arms with extra caster to compliment the PS. I want a good cruiser that I can get "fun" with up in the local mountains/twisty roads, as I love doing that.

Thanks all!

i would say electric and rack are out. power steering box will normaly have a faster ratio lock to lock. you need to know this info as well as the turning radius. there may also be bump steer to consider. pump brackets are critical. pump runs all the time so if the brackets are junk they will break or bend. also need to be sure of which water pump and pulleys are needed.

70 L camino, grampa engine, g-force 5 spd, road rage suspension. Pray first before all else fails.

Hello Mike.

I went with the CPP 500 box and Ididit retrofit column in my '56. I have Headman coated headers with no clearance issue. I switched from a 605 box, and it was a huge improvement! This was in 2012 there are still no leaks, drips, etc.

I didn't want to spend the money to get a rack system.

My two cents worth... :-)

I also went with the 500 steering box and a retro fit Ididit telescoping steering column. I have Patriot headers. Still works fine. As mentioned above, the 500 box is a huge leap forward from the 605.

I went with a borgeson box and a ididit tilt column first. But the tilt column was too long for me and i bought a non tilt. Much better.
The fitment of the box and the column is very good.
Only the attachement of the column under dash is a little bit tricky. I do not use this self tapping bolts.
I bought a borgeson box for my mustang many years ago with a fault in the sealing. But the second one for the mustang was good and the one for my bel air too.
I run sanderson mid lenght headers in my bel air with more than one inch space between headers and box.
Between pitman arm an headers 2/16 of an inch. With the steering wheel complete turn left.

Hi Mike, I too am involved trying to figure out a power steering set-up for my 55 Nomad. Can of worms is this project. After all is figured out, do not forget the upper control arms for the right caster. How about making the dash trans gear indicator work with the right column. Seems the so-called right column has issues. Also no matter what pieces you use there will be a problem/hiccup with something, somewhere. I have not heard about easy makeover yet. Fun with cars I always say. Good luck, I may pass on the whole deal.
