Bob & Larry:



When I was redoing my K convertible, years ago, I was looking for a set 
of seat belts and the mirror base for the right side exterior mirror.  A 
guy at work, sold me a 64 New Yorker, that he had crashed.  It had the 
belts and mirror I wanted.  The car also had a tilt steering column.  I 
took the column and stored it in my garage attic for 30 years.  Fast 
forward to last year, when I bought my Ram K from Bob.  It had a tilt 
column; but the steering wheel had severe cracks and I kept pinching my 
fingers on it.  Also, the horn ground through the steering column was 
shot.  When I pulled the New Yorker column out of the attic, I was 
delighted to see the wheel was in nice shape and the same color as the 
original.  I also noted an old piece of wire hanging from a bolt affair. 
  This turned out to be a modified dome light ground switch from the door 
jamb.  Some old time mechanic had outsmarted the copper ground strap.  
After I removed it and studied it; I realized what he had done.  He cut 
the dome light switch shaft at the electrical connection end.  He then 
removed the shaft and reversed it in the switch body.    So now  the 
flat contact piece that used to contact the door is now spring loaded 
protruding from the threaded end of the switch.  Finally he bent the 
amputated end of the shaft over, so the shaft is held into the body of 
the switch.  It also becomes a  convenient place to fasten a ground wire 
to complete the  ground circuit.  Once the modified switch is  screwed 
into the steering column,  the old internal spring holds the plunger 
against the inner steering shaft and you have a constant ground, no 
matter that the steering shaft is rotating.  Conveniently the tilt 
steering column has an access slot machined into it.  The old dome light 
switch was the exact size to allow me to thread it into the slot with a 
socket and ratchet.   On a non- tilt column you would probably need to 
drill and tap the outer jacket for the switch.  I don’t have the picture 
I had of the modified switch; but here it is on the K. See

Hope this helps

     The copper ground strap is my guess.

     See http://www.chrysler300club.com/how/62horns/1a.html



and

     Is a boat load of work to replace that strap.



     Bill Elder came up with a way to drill into the shaft sleeve 
exposing the

     shaft and getting the shaft to ground that way. Ask him for details.
