Does anyone know if a 1968 Cutlass package tray would fit a 1966 Cutlass?

My car already has dual speakers installed, so I figured I'd keep it if I could make it look somewhat original. Otherwise I am going back to the factory single rear 6x9.

 

no...... not even close

 

Maybe if you cut in half lengthwise.
66-67 are not nearly deep enough
as the 69-72 S style body.

 

Good to know, thank you for the replies. I figured someone would know
