Here's a heads-up that may save someone some aggravation I had to use new Goodmark doors on my '68 and when I tried to adjust the windows it was a nightmare. I spent literally hours trying to get the RS window to fit the weatherstrip and align with the roof rail, but no matter how I adjusted it, it would not raise up high enough in the back to fit right. Also, the front edge of the glass would hit the door.
It turned out that the slots for the window cam had been punched a good one inch off the mark and had to be elongated, and I had to grind the door for clearance where the front of the window passes up out of the door. Hope this helps someone!
