Inner firewall insulation - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Big Blue · 05-10-2005, 09:24 AM

Didn't know where to place this question, so if its in the wrong place please move.

I'm looking for or some other way to replace the insulation that was on the inner firewall under the dash.. I'm gutting out the cab for painting and want to replce this.
What other means have some of you have done?

Thanks John

I got one from chevy duty http://www.chevyduty.com/frame-store.html for about $100. Do a search for 42-041, that's the part number for 73-79s, even though it says 73-87. Mine actually came from here though http://www.quietride.com/. The fit and finish was pretty good, but not perfect, and you have to punch out holes for the a/c and the throttle cable and such.

If I was going to do it over, I think I would go for some dynamat, because I think it would be easier and would do a better job of getting rid of noise. Some of the dynamat has a heat reflecting layer too.

Thanks truckinbean,
Yea, I seen that in the chevy duty cat. $100.00, thought their might be a better but cheaper way. I plan on putting the other stuff on he floor to cut down on noise and heat.
Still looking for other suggestions.....
