Seeking original style underlayment - '73 Camaro

[hubleyman]

Hey gang,

I am looking for a source (hopefully precut to fit) for the original very heavy thick style tan paper-faced (maybe it's sort of cloth faced?) tar type of carpet underlayment or sound deadener for my 1973 Camaro. Please see pic as an example.

Haven't had much luck in surfing all the typical suppliers websites, or Ebay, or forums. Some of the suppliers describe what sounds right, but the pictures don't look like it.

Not interested in the cheesy lightweight sandy roof felt type of stuff that almost everyone supplies.

Also would rather not use the paper-faced rubber type of sound deadener that I have seen, but it seems better then the thin asphalt stuff.

Any guidance or suggestions would be greatly appreciated.

Charlie
