Confirming correct part and where to find another

See attached photo.

I’m trying to confirm that I bought the correct part to replace this (circled in red). I believe it’s the passenger side steering knuckle. I ordered the following from RockAuto: Dorman 698150. Is this the correct part?

I also need the castle nut that secures it to the UCA (yellow arrow). Does anybody have a part number for that or know where I can get one?

Thanks

 

Ok nvm so I just discovered partsouq and found that I just need the UBJ assembly

 

If you feel the need to apply heat to remove that ubj, stand out of the line of fire.
Pressure built up in the ubj and blew the top off like a cannon.

No animals were harmed, or fingers lost, in the process.

 

It might be a good idea to thread a nut to the ball joint before you try and remove it.

 

Wouldn't have helped.
I had borrowed a press kit and due to the orientation of the bearing nothing fit from that kit.
