Heater Box Foam Question (1 Viewer)

[BigDogg]

Performing a refresh on my original 1971 FJ40 heater box. I have read most of the heater threads on mud and they say to use 1/4 charcoal foam. One thread referenced using open cell, another closed cell, and a third mentioned neoprene. Any thoughts on the "type" of 1/4 charcoal foam?

I used window AC foam filter, has worked pretty good so far.
