Inside Firewall Insulation

Finally got around to pulling the heater box on my '76 to replace the core. As shown in the attached pics (and as expected) the 40 year old insulation behind the plenum assembly is garbage now. I am wondering what would be a good replacement using modern materials? Can't find any reference to this stuff anywhere. Any ideas?

Re: Inside Firewall Insulation

My plan for my vette is to put a coat of this
