That the AMT '62 Buick Electra and the '61 Chevy bubbletop windshields seem like they might work. I do not have an actual JoHan kit to check, just the various resin bodies.
The rear windows will be different from the Olds though, so you'd still need to make one from acetate. Just play around with a paper template first to get the shape.
Some of the other kits listed have windshields shaped to fit their bodies in a particular way, and won't necessarily interchange with other kits.
