Ignition switch mechanism / 5ktq assembly wanted

[Leif Pedersen <leif@mail.execpc.com>]

My 1987 5ktq will not start when the ignition key is turned.  Switch was
replaced 2 years ago and worked OK but always engaged the starter just
before the key would hit the stop.  Now no starter engagement, key only
hits stop.  Have instrument pod out and can start car every time with a
screwdriver in the switch.  Also tried a used switch out of a wrecked car,
same problem.  Conclusion:  The actual key switch mechanism that engages
the switch is worn excessively.  Does anyone have any experience with this
assembly?  Can this assembly be taken apart and is there a relatively easy
switch or do I need to replace the whole assembly?

I will be going over to the mechanic to look at his Bentley, but I don't
thick that there are any serviceable parts.  Any suggestions or if anyone
has a spare assembly that they would like to part with, please email me and
include ignition switch in the subject.

Thanks for any and all assistance!
