I'm installing the Al Knoch heat barrier that I purchased for my 66 roadster. The barrier is jute covered with a roofing paper like rubber or vinyl top layer. I was told that this pretty much replicates the original underlayment. Included in the kit is a small piece that fits on top of the transmission tunnel from the firewall to under the radio and radio console. I didn't notice any underlayment here when I stripped the old carpeting. Installing this under the radio would make the radio even more difficult to remove and I'm inclined not to install it or cut it back to in front of the radio. I could see where a heat barrier here could be beneficial. Comments are appreciated.
