Steering box bearing

[SRU1436]

Hello, I am replacing the output and input shaft seals on my OEM power steering box in my 72 C10. It appears the seals have never been replaced as the output shaft seal is hard as a rock and I’m having difficulty getting it out. In doing so, I noticed I must’ve boogered up this bear when I was dissembling it. It still rolls, so it appears the function of the bearing is not compromised. I’ve searched the interwebs and I can’t find a replacement bearing. Additionally, any recommendations how to replace the seals. I’ve followed Txfirefighter thread on replacing the seals, but can seem to get the seals out. Thanks, Matt
