Firewall Insulation

[burban_kraut]

I have the metal dash removed on my 1991 Suburban and the insulation that is up near the windshield behind the dash is falling apart. Is there a pre-cut replacement available for this? If not, what should I use to make my own?

FYI, this is not the insulation that is behind the heater box below the dash area...

Mine are usually falling down too. GM used that insulation for all sorts of applications in the 70's, 80's and 90's. The bad thing about it is rodents LOVE it, I personally would find something else to use in it's place.

I was thinking of using Dynamat or similar in mine.
