1963 Globetrotter Window Sash Measurements

[rfandy]

You know what they say, measure twice, cut once!

I've measured the rear window sash five times with the idea that it is same size as front. I don't have a front sash so that's why I am measuring rear. I've come up with 21-3/4 H x 42-3/4 W. I've looked at Vintage Trailer Supplies listing of available pre-made sashes and this size doesn't exist. I've measured the side windows (18-3/4 H x 28-3/4 W) and they have those. They're telling me I've incorrectly measured rear?? Does anyone have a 1963 Globetrotter that they can take the outside measurements on the front and rear window sashes for me?? I don't happen to have a 2nd one lying around .

Thanks!!

PS - I saw some postings of locking clip drawings. Has anyone started to make them yet?? If so, where can I get some??
