Whats the difference between 66 & 69 steering Columns?

hmmmmm...ok.
I am trying to determine which Grant Wheel adapter kit I need to order. I have a Grant kit now ( don't know what its for - but it looks like a kit for a 69)....but it does not match where the horn brass roller wheel hits the hub on the kit....

All the pictures of the Grant kit for the 66 looks like it will work.….but Im afraid it wont line up....

Thanks
