Hi all Im working on a 71 Duster and the ignition switch is super stiff to turn when starting car . and you have to pull it back manually to shut off car. Where ever you let go of the key that's where it stops. there is no spring assist at all. The 2 ears on the tumbler have been broke off by previous owner. Im afraid Ill break the key next. Any help? Is there a switch at bottom of column that is binding? I cant locate my manual right now for a pic of exploded column. Thanks
