How do I replace ignition switch '70 Dart Swinger

Great! I always like to take things slow and check out all angles to fix it before I start diving in to things. I used Standard Motor Products US88 Ignition Switch. Just a thought, I sprayed some graphite powder all over the ignition switch cam and cylinder before putting it all back together. Brand new I know these switches can be a bit "sticky" or rough, and I guess the graphite powder helps smooth things along until it gets broken in.
