1970 Ignition Switch

I took my steering column apart yesterday to work on the ignition switch and found the shaft was dirty. The ignition switch spring couldn't get the shaft to fully rotate so I cleaned the switch with WD40 then sprayed the shaft with lithium grease and now the shaft fully rotates. I also cleaned the lock cylinder and lubricated it with graphite. The ignition now works properly. Thanks for your help guys.
