Hopefully looking for someone who sells sheets of tar underlayment with the adhered paper backing similar to what they originally used at the factory. Need it to make a set for a '70 Camaro. REM once used it for their reproduction die cut sets, but no longer for certain models. Deadnuts.com (Mustangs) uses paper backed for their '69-'70 fastback trunk underlayments.

If someone should happen to have a '70 Camaro set with the paper backing for sale, PM me.
