Default converting 69 to power steering

As I get older, I'm finding it harder to steer my manual steering 435 car and want to convert it to power steering in the future. The caveat- I do not want to use the stock cylinder style power steering. Is there a power steering steering box that would fit and if so, do I need to change to a different pitman arm?

look at the Borgeson box and the many posts on this forum concerning its installation.

Thanks for the info. looking through the instructions, shortening the steering shaft by hammering on it has me concerned.

Borgeson, 12:1 ratio, less turns lock to lock, no leaks. No car modifications.

Isnt it funny if that kit didnt exist and some cat was doing it himself and suggested using a hammer to of all things shorten the column, the thread would light up with people calling it hack job or " bubba" as is the term for hack jobs here,
But since it's presented as a kit i guess its no longer a hack job,
Heck if i had the money i might do it...

I am curious what jim shea the gm corvette steering guru would say about the shortening the shaft,

I agree. Shortening the shaft by hammering on it would destroy the collasablity function of the column. I would rather dis assemble the column and install a correct length shaft.

3x2,
When i said if i had the money i might do it, was an inside joke on myself,

When i had my car at a techs shop he did this hack to get the rag joint installed and it is a heck of a stone in my shoe to my OCD,

To my understanding the column can be pulled back out but hammering it in breaks some clip,

well it doesn't destroy the collapsibility it starts it . I always thought the two shafts were put together during construction and plastic was injected into the overlap thus holding the two pieces together.
Lots of people have done it , I have driven a friends car before and after installation and its actually way nicer to drive with the mod.

I liked it so much I'm doing one for myself now .

Whatever amount the shaft is collasped, it is that much less the shaft can collaspe in a collision. That scares me.

For those who have done the Borgeson mod, does it eliminate the freeplay that exists in the original setup?

I have read posts that state that there is still some freeplay in the steering with Borgeson, and if that is true, I will stick with my manual setup.

I really enjoy the way the car steers now that I switched back to non-power steering. I love the feel of the road, the feedback on tighter turns, and the precision of a steering system with zero play. With my Gary Ramadei built steering box, its awesome and it truly makes if fun to drive. I live with the parking lot effort to have the other 95% of the driving experience.

You should test drive a C3 that has the Borgeson unit.
You need a good alignment which means you need a good front and rear end. Ball joints, tie rods, strut rod ends and so on.

I dd my manual steering 66,
Truth is my 87 fiero is harder to turn parking than that 66 was, and the 66 had like yours no slop,

On my 69 if the power works i will keep it til it leaks, then do what you did,
Its been sitting might leak from day one,
But i will toss the old power parts in my basement and get the manual stuff from howard,

Didnt you have your stock power parts for sale, hum, might be a option for the op

I have a 71 with the Borgeson and a 72 with stock power steering , yes the vagueness will be gone.

If the 72 was not such a low mile original car I would make the conversion.

You don't have to use a hammer, it just makes it easier. You could use your hands if you can get the right angle on it (or remove the column as might be necessary anyway). Using the hammer as shown in the instructions is just a few light taps and not full swing blows.

IIRC from my install there is more than 3" of collapse in the column and you would be removing about 1" so there is still roughly 2+" of collapse left anyway.

https://www.corvetteforum.com/forums...n-options.html

Whatever amount the shaft is collasped, it is that much less the shaft can collaspe in a collision. That scares me.
My .02 on the potential safety issue of a reduced collapse.... we drive a fiberglass death trap anyway. Anything more than a love tap will kill you regardless of the amount of steering column collapsibility. I don't believe anyone in the history of time has stopped driving their C1 or C2 because lack of a collapsible column.
