I don't believe so
56 has a gasket for the hood ornament 57 does not.I just got mine repainted and it had a thin gasket between the rocket and the hood. You might do a bit more checking.
No seals originally, but may be a good idea since they sit directly onto the paint🤔 I sense an opportunity to create one.
That gasket is aftermarket only, Never a factory part.56 has a gasket for the hood ornament 57 does not.
This would be just under the lip where it sits on top of the metal. Will give it a shot tomorrow before I squirt more paint.I seriously doubt you can use a gasket of 1/16" or even 1/32" thickness - the rocket will no longer fit in the hole.
