MG Car Repair: headlight & Ignition switch, steering wheel, steering column

Question
Is there a video or pictures available on how to replace the ignition and/or headlight switch on a 1977 MGB?

Answer
Hi Chuck.  I am not aware of any video or pictures.  

Changing the headlight switch is straightforward, but you have got to drop the steering column in order to undo the 4 screws that hold the cowl around the column, and you may have to remove the steering wheel.  PLEASE BE CAREFUL - the brown wire is permanently live, and it is not protected by a fuse.  

Changing the ignition lock is a problem, because it is part of the steering lock mechanism, and the lock is bolted to the column using two 8mm bolts with shear heads.  To remove them you must drill the heads off.  

If this is not clear, come back to me.
