...but they interchange, and as I understand some 1:1 Chrysler products were offered with both styles through about 1963. The '60 DeSoto brochure shows the car with the "browless" windshield as in the Chrysler kit. A buddy of mine built me a DeSoto years ago with the Chrysler glass, to match the brochure picture.
Another glass to look at would be AMT '57 Chrysler. I believe the "new" for 1960 Unibody cars were not all-new, but basically reskinned '57-'59 bodies with parts of the frame welded to the lower body. The '57 windshield area looks a lot like that of the '62.
A "wait and see" idea would be the (hopefully) coming Atlantis '62 Chrysler convertible, but who knows if that will materialize. Whatever the windshield comes from, AMT '62 Bel Air rear glass should work in the '62 Chrysler.
