the 67 kit did not come with an ignition, and 65/66 kit does. the 67 kit was cheaper.
ok, they looked to be the same diameter, and the mechanism was on the same side. I have no ignition in my car, I welded the hole closed and now use a push button ignition on a painless switch panel. I could use the spare key, but don't need the ignition. The price wasn't that much more, just trying to save a few bucks.
