part number help tilt column 72

[gn4u2c2]

yes I used the search feature but no clear anwser
I work at GM dealer but parts guy is not able to locate these older parts without the #'s they no longer have the pre 82 microfilm or books.

I need the cancel cam for tilt
I need the upper steering column bearing, for tilt
I need the upper thrust washer(wedge washer) for tilt
I need new upper thrust washer/wedge nut

I understand the race is not avalible if anyone has found a suitable replacement please advise thanks

If you do not have a anwser please don't post trying to keep a clean neat to the point thread thanks.
