Hoodliner material - where to find?

Hey guys...thought I'd throw this out there to see what I can come up with. Basically, I'm looking for the material used in the past to make a hoodliner for my 65's hood. It looks like the old style dirty padding. What I'm wanting to do is get some material and cut out the triangles and such that make up the underframe work of the hood and adhere the triangles to the hood, leaving only the framework exposed.

I searched on here, but I only came up with a thread from someone looking to do one on a '69 but it was an unanswered thread. I've gone to Earmark car audio and they carry a Stinger hoodliner product, but it's wrapped in foil and I don't want the shiny look. I haven't seen any other color choices available - just the shiny foil wrapped stuff. I think dynamat carries the same idea, but I think it's the same thing with their name on it.

Any suggestions where to find this padding material and how to adhere it to the underside of the hood, since it will have to deal with engine temps? I thought about just going to a junkyard and ripping one off an old car and cutting it up, but the integrity of the material might be compromised when I rip it off, and the fact that it'll be old. Thoughts??
