Yes, I will measure and post pics. The one I found has a metal head that is put through from the outside of the window, then the flat nut. So that the extra threads can get the metal track the regulator arms rides on and another nut holds the track on. The others will have a black plastic head (about 1/4 high) or a blue head (about 3/8), that are meant to ride on fabric covered metal guides when the windo is rolled up. Have not found those yet. If you can get to the other window and see if the heads are metal, black or blue, that will help a lot.
