I don't have a glass as of yet. I was using a plywood templant. I tried the dart regulator but could not get the window down all the way. As you see by the date on the pics I haven't messed with car for a while. I got involved with a 67 D-100 the last 18 months. I am just now getting back at the wagon. I will play with it some and get back to you. Thanks for the help. I would like to get it done in time to drive down to Ocala in the fall.
