The ignition switch on my F250 has finally worn out. Parts list shows D1AZ-
11572-C and the one I received as a replacement is a D1AZ-11572-A.
The -A seems to have a stud out the back to hold the plug tight and the -C
doesn't seem to have one. Got any ideas?

Did you try your frindly local parts place? I would recommend NAPA, mainly because I bought a cheapie from another place, and it blew apart on me. It was only a month old, and all the guts came flying out. Get a good one, and it'll last, and you wont have to worry about it. Mine has that stud on tha back too. Try telling them it's a 72 next time.

 

The one I got was from Vintage ford. I'll check with them again about a 72 switch thanks for the advise
