Sometimes you have to go metric sizing to get what you want if it is a hard to find bearing. That's what I had to do with the USA made 60 year old milling machine.
 You might start a search here-  https://www.nodeshk.com/timken/catalog/

I've used a lot of SKF bearings and have been very happy with them.
I would guess you may have a double row/angular contact bearing to take the load.

I have the brass retainer plate unscrewed but it is being held up by the steel thing in front of it.  Is that the part you above you said to pry off??


Also I did see where the brass retainer was very lock on and once I started loosing it then it was spin freely.  So should I even mess with it taking it all the way off???

I am not sure what you mean.  To old to remember exactly what it looked like -- did the brass ring stay on or not.  The whole unit can be remove from the casing,  That is when I oiled the bearings.  The bearing are kept on the shaft with e-clips and should be remove with special tool -easier than trying them off.
Like I said once oiled the bearing were fine and a lot cheaper than new bearings.  I would try the oil first.
Don't want to take it apart,. but I could if you need pictures.

Then I screwed the brass retainer back down and it works fine so I will leave it as is for now.

to help you understand the inside of the live center I found this on line, it is a oneway but the PM is the same and the thread is a 3/4 x 10.  I made several things and taped them 3/4 x 10 for holding odd shapes. I assume you have the cone point for yours . one nice accessory is the oneway large bull nose that can be reversed as a cup. oneway https://www.amazon.com/Oneway-Bull-Nose-Cone-Centers/dp/B07SRHDVRR/Oneway Bull Nose Cone  very handy

link to oneway bearing replacement not sure if it was the bast way to go about it, But it worked for him. I never had to take mine apart. http://lehighvalleywoodturners.com/wp-content/uploads/OneWay_live_centre_bearing_replacement.pdf
