<VV> Switch change

[GYoungwolf at aol.com]

I have a customer who wants to be able to drive his car without using the 
ignition key. He wants me to install a hidden toggle switch to energize the 
ignition. The car is a 65, so I am thinking I can swap in the
earlier ignition switch which does not need the key? Without any comments as 
to whether this is a wise
decision, I would like any tips on the wiring changes that might be needed.
Thanks,
Grant
