Did Factory Use Insulation in this Cowl Area?

Yea not on early A's that I have seen. All 4 of my early A cars had no insulation there. A 64 and 2 65 Barracudas and a 66 Valiant (Canadian version).

Of course the OP can always put some there, especially since he's not using the factory style firewall insulation anyway.
