Re: 1969 GMC.. right off the farm
I ordered some Siless 157 mil sound and heat foam insultion, and also 80 mil sound deadener. I have doubled these up in some places, while in others just used the sound deadener (like behind the gas tank). I am planning to do a layer of each all the way up the firewall. My carpet is also mass backed.
Looking for any suggestions on what to plug the firewall holes with that were used for the old blanket insulation.. thinking maybe some plastic fasteners?
Ordered a new glove box decal off ebay since I accidentally deformed the old one when removing it for paint. Also installed my new dash pad
