1972 Ignition switch

[jaytr6]

It seems the ignition switch I put in 2 years ago has failed. It is TRF PN LU39415. I can't find the notes/instructions I had for removing the switch. It is mounted in the lower edge of the dash below the steering column and has the big rubber protective cylinder around it. The Bentley does not seem to include this version of the switch. Is there a resource that covers this? Can I leave the key part of the switch attached and just push the black plastic sleeve off the back to free up the electrical switch? Thanks.

That black plastic sleeve is all that holds the switch onto the key lock on mine. Some cars apparently have a small set screw on the key lock assy that also holds the switch in place.
