66-67 window regulator identification

[bellsbluff]

I'm clearing out the last of my extra parts and ran across a set of window regulators that I think came out of a 66 - 67. (They were stored in a box with 66-67 door latches and releases.) Can anyone tell me if there's a easy was to tell the difference in the 66-67 and the 68-77 regulators?

Here are pics of lh and rh 66 regulators. Hope that helps. Also note no threads in the window crank shaft.
