Does anyone know where I might find a schematic showing where the various decals go in a 1970 Cutlass Convertible?

 

Most of the decal locations are in the 1970 Cutlass Assembly manual. I presume you're looking for tire pressure, jack stowage, limited slip, jacking instructions? Or are you looking for the decals under the hood?

 

The decals that go under the hood.

 

Sorry for the delay getting back, life was calling.

The information you're looking for is located in the 1970 Cutlass Assembly Manual in Section 0, Page 108.
