I purchased an NORS bearing off of e-bay after confirming the GM part number for a 62 C10 upper steering bearing. The new bearing is identical to the one that came out of my column except the plastic on the new one isn't all cracked! I'll attach a pic of the part along with the GM part number (on lower right side of box - 5672508). I'll also try to upload the instructions which may confirm that there is a difference in the application depending on what year your column is and whether a passenger car or truck. I have not installed the steering wheel yet, but given that the bearing is identical, I'm pretty confident that this bearing will work. I don't plan on using either the spring, seat or the o-ring since my column did not have them when disassembled. gmpartswiki.com is a great source for parts numbers. Hope this helps.
