67 window handle just spins... what to replace?

The driver side window door handle on my 67 FB just spins and doesn't move the window up or down. The gear drive side that the handle screws on to is not stripped. I pulled the door panel off and it appears that there's too much play with the drive (I could always wiggle my handle around in every direction previously). I believe the gear drive is riveted on the inside.

Anyone been through this? What parts do I replace? It seems as though the gear drive is attached to components in the door?

Thanks!
 
Put a new window regulator in. Don't get a 68 regulator, it will work but the splined shaft that the window crank handle screws onto is fatter and the crank will not engauge all the way and you will need a longer screw.
