non-ac heater core

[hardknocks]

i removed my housing that holds the heater core. when i did the cardboard backed insulation ripped and was water soaked and tore up. very unusable. where could i get this piece at to seal up the housing to firewall ? or what would be a good substitute? thanks alot guys.

LMC sells it. Or you could cut up a welding blanket.

I used generic foam insulation tape.
