Canceling Cam Differences Tilt/Fixed?

Hey Guys,
Years ago i purchased a canceling cam from laysons, for my 69 Dart. I am reassembling it now and noticed the package said: Canceling Cam with Tilt Wheel, so I must have got the wrong one. My question is what is the difference in a fixed 67-69 column cam and a tilt 67-69 column cam? I have never seen a 67-69 A Body with a tilt. Will it work?
