Thickness of rear bulkhead board/foam?

[JohnnyK]

Hey guys,

Wondering if anyone could tell me (ballpark) the thickness of the rearmost interior board/bulkhead board that covers the firewall. Parts diagrams seem to overlook it.

Just wondering if it's, say, 1/8" hardboard, or 1/4" plywood, etc? (Foam thickness would be great if anyone knew that one off hand!)

Thanks guys.
