If you have an emblem and an 85 Cutlass, then I'm sure you can.
Will it fit right? Not sure.
Either drill holes, or cut off the mounting pegs and use some adhesive or emblem tape.
Never heard or seen that happen.
If I were GOING to put an emblem up there, I'd find a more modernized rocket emblem, maybe from a Ciera or delta/98. But that's just what I would do.
