Father-Son 1974 Duster Project
If I remember correctly you pull the wheel take the screw that holds the turn signal switch out, pull the switch a little bit then you can get at retainer screw for the handle.
When I was playing around with my old column, I put a screwdriver behind the turn signal arm and just bent it right in place. I didn’t wind up using that turn signal arm but I guess you can bend it right in the car like that. It does not put up much of a fight.
