Is this thing ALL ELECTRIC assist, no hydraulics? Or am I looking at this wrong?

Here is some more work I did on the steering column if anyone is interested.
This is for weight reduction. I wouldn't recommend for a dd.
This is the steering shaft stripped out of the column:

The steering shaft weighs 4lb 6.5oz

It's going to be hard to steer with this joint in it![Smokin](https://ls1tech.com/forums/images/smilies2/smokin.gif)

Bearing and clip installed. I cut off the steering column housing at the weld.

Now we are at 5lbs 5.25oz including shaft, cutoff housing, bearing, and clip

I think it can be lighter. I cut out the weld and slid the shaft further back into the bracket.

Now it is about 9 oz which is almost a half pound lighter than before. it still has the bearing and clip installed

The sheer pins are made of plastic and you can just drill them out. I was trying to find a piece to couple the shaft that was the same size ID and my friend suggested just cutting off the lower shaft. That is what I did and it fits great and I got a 3/4" tube for the shaft and a steering shaft bearing that will be used to mount it to the car. I will need to make a bracket for this still.
It currently weighs less than 4lbs with everything, but I still need to make a bracket. Right now I have about $32 in it.
Here is the steering shaft with the sheer pins out and the cuts I made. The two parts on the left will not be reused. The only reason I took the two left pieces abart was to make sure the lower portion was hollow before I cut it off.

Here is how everything will fit together besides the middle bearing. Also the shaft needs to be cut some because it is too long right now.

Here is everything together except the bearing is laying beside it because it is a tight fit and I need to measure before putting it on.

The final weight of my steering column/shaft is 3lbs 8oz including the new bearing. I made a new bracket to mount the bearing to in the car, but it weighed the same as the old one I cut out.
This is a loss of 12lbs from the stock column.(excludes steering wheel and air bag, that would be more loss if included)

Electric Power Steering (EPS) for less than $200
I took a slightly different approach and used an EPS system from an Equinox/Vue. No hydraulics, no fluids, no leaks.
I recently installed electric power steering in a 1966 Mustang. I did not use a kit, I simply pulled a column style EPS from a newer GM vehicle and then spliced the unit into the original steering column.
The results far exceeded my expectations and the cost was less than $200. I designed a controller that automatically adjusts assist level based on vehicle speed, so that the steering feel is "just right" regardless of speed.
I documented (with pictures) how I went about this on a Vintage Mustang forum. If anyone is interested do a google search for "Best $200 mod ever (EPS)"
or
follow this link to page 7 where the details start:
