I'm wanting to replace my ignition switch housing on my 1972 F250. I added the 2 ranger trim pieces that go on either side of the steering column, (my truck is not a ranger, just liked the look) and when I pulled my ignition switch housing I didn't notice any special ways that it needed to be mounted into the ignition switch mount. The mount has a hole in the bottom where it is screwed into the lower part of the dash. It's a small phillips head screw, and there is a slot where it screws in to adjust the mount in closer. The mount also has a notch in it for some reason, at the bottom of the hole that the ignition switch goes into.
My questions are:
1). Does the notch in the ignition switch mount serve a purpose? Does it hold the switch housing from turning? (Item D4 in diagram below)
2). Beings I added the ranger trim, do I need to adjust the ignition switch housing out?
3). I noticed on a Youtube video for a chevy truck they added grease inside the ignition switch housing (couldn't find any info on the old Fords). Does this need to be done? and if so, what type of grease should I use.
4). Any other suggestions or tips you can give me on this. Thanks

The problem I was having with my ignition switch, was that after I added the trim and put my original ignition switch housing back in, my truck would start, but I couldn't get the engine to stop when I turned off the ignition switch. I pulled the coil wire off my distributor to get it to stop running. Would this cause any other issues? Here is the Dennis Carpenter diagram that shows the parts I'm talking about: https://www.dennis-carpenter.com/exp...nition-switch/

 

Yes an yes to your first question, the notch prevents the ignition from spinning when tightening the bezel. I replaced mine but mine did not have the mount that you show in the picture, that could be the reason it was loose even when bezel all the way tight. I put an oring between the bezel and dash and that worked well for me. If you plan to do any rewiring you wont need the special connector you can just use insulated female spade connectors.

 

Thanks stewchi. Has anyone else changed out their ignition switch? Any other inputs?
