50's GM Rear Window Glass

I have a curved, rear window glass from what I believe is an early 50's GM product. There are no markings on the glass. All I know is that it does not fit my '50 Olds model 76 coupe. Is there a way to determine the car(s) that this window might fit? I would like to get rid of it rather than have it lay around my shop. Any info would be helpful. Thanks!

 

How about some dimensions?

 

Dimensions are 44.5 inches wide by 16 inches tall. There appears to be a 2.875 inch offset/bow in the center of the glass.

 

looks more like a 98 olds with those bottom corners .PM me I have a used back glass for a 50 olds 88 cpe
