1998 88 Turn Signals won't cancel

1998 88 LS Turn signals will flash but will not cancel when steering wheel is returned to center. I assumed this to be the standard GM "cam" that needs replaced in the column. Looking at on-line parts sources, it seems the switch is integrated and now costs about $50. Ugh.

Obviously have to remove air bad and the steering wheel. I've got the tools for that.

Does anyone have any tips/tricks/instructions for replacing this thing?

Autozone.com, repair guides has the basic how to.
