The PCV strips fit most of the windows on my 1960
Safari. There are two different types of window frames on my AS. I think the manufacturer used various types of frames at that time.
The PVC was a little loose on my window frames, so I ran a very small bead of vulkem to keep them in place.
VTS used to sell a variety sample pack of short lengths of various weatherstrips for just this reason. That's how I figured out what to use.
