2 ignition switches and still no run

Trying to look something up on NAPAs website is infuriating.

67-68 Dart switch, a little over 16 bucks : MPE KS6528SB

or a little over 20 bucks, ECH KS6528

69 doesn't seem to be shown

I wonder if you could tear apart a 67--8 switch, put the switch guts in your 69 housing?
69 housing is a different size housing.....Valiant & Dart are the same
