This car came originally with manual steering and the previous owner converted it to a 605 power steering setup.
I'm trying to figure out how it was all cobbled together.
I was hoping someone could Identify what I have to work with and what I need to make it right.

The pics show the issues that are causing a significant amount of play in the steering wheel.
The rag joint (incorrect... no ground strap) looks like it's bolted (with a low grade bolt) to a homemade part on the bottom of the steering column... maybe not.
The Center/drag link appears to be the original manual steering part.

Any help would be appreciated.

There are repair kits available to repair the rubber coupling of the rag joint. The grade 3 bolt is only to keep the shaft in the rag joint. Of course I would use a grade 8 anyway, but you can't tighten it enough to eliminate the slop. The double D on the shaft should be tight, to prevent ALL slop. Apparently someone has ground or filed it down, too small, when adapting the shaft to the rag joint.
The drag link can be adjusted and there are cups that go around the pitman arm ball that can be replaced.

Thanks for the reply Don.
I would prefer to replace the rag joint with new.
The one that's in there appears to be riveted together, doesn't have the ground strap, and it may be wollowed out at the double D connection.
Doesn't seem worth it to me to mess with it.
There appears to be plenty to choose from at various suppliers.
I just don't know which one is the right one.
Can you tell which one I need by looking at it?

The pitman and idler arms seem to be fine.
It's the center link that has all the slop, right where the pitman arm connects.
Is there an adjustment to take out the slop there?

Center link repair kit. Link to kit.
The steering box is a 3/4"-30 spline connection. Measure the diameter of the steering shaft. It looks like it may be 3/4". The rag joint will be the diameter of the shaft xx"-DD.

It provides a solid ground for the steering shaft to ground the horn ring.

Out of three shafts and gear boxes that I have none have ever had the ground strap. I would have thought that ground would come from the steering mount on the dash??

ozzie7,
I purchased my rag joint from CPP.

The grade 3 bolt, I thought should be there for a safety reason.
On a front end collision, the bolt is designed to snap and not push the steering shaft/wheel straight back into the driver.

I'll be Frank, this hobby isn't getting any easier.

The steering shaft provides the ground for the steering wheel. The steering shaft is mounted on bearings and the bearings may or may not provide a good ground.

How far would the shaft go into the rag joint when the bolt snaps?

Watch what happens to this shaft about a minute into the video.

I'm just saying a grade 3 bolt will do NOTHING for safety. The shaft will be driven into your chest by the steering box 1/4" after the grade 3 bolt sheers off. At 120 miles an hour (both cars doing 60mph), 1/4" isn't going to make much difference.

Not cheap but it will allow me to add the ground strap pretty easy.

The new rag joint should be here by this weekend.

I was wondering if someone could share the "Easy Way" to remove and replace it.

I have the '58 and '59/'60 Service manuals but the info doesn't help me as much as I hoped.

So I thought I would ask the experts with real world experience before I just start tearing into it.
