Hood insulation Poll. Yes or no?

Available with the full undercoat option, J55, as I noted above. MAY also have been part of the "california car" package for noise suppression, where they took away chrome tips, unsilenced air cleaners, added resonators and the likes...
I don't know if the option was offered pre 70. I know every Mopar we owned all had them. Is J55 on your fender tag?
