I've got a 1968 Imperial with tilt and telescoping wheel. Started working on vacuum parking brake release and reverse light switch. Pulled steering column and discovered that the bottom bushing was not engaged so shaft wiggled about and no amount of adjustment at the switch would help. At a glance I can't see a way to engage bushing its at least a 1/4 - 1/2 inch out. I know someone out there has done this before and I need a little help please.
