My 1975 GMC Jimmy came with a spare tilt wheel steering column with the column shifter for an automatic.
I don't know the year of the spare column, but I am trying to find out.
I've removed everything I can see and have tried to jimmy it out, (no pun intended), with a screwdriver but to no avail. I
don't have the key for the ignition. Below are some pictures.


Here I've circled 3 areas, the top two look like they may need something done to them to get the cylinder to slide out? The lower circled area has a small bolt down in there but it's so far from the ignition cylinder I don't think it has anything to do with securing it.

Could take it down to the machine shop at NAPA if I need to, have to go there to get a new ignition anyways.
Thanks ahead of time for any tips.
Mike
