I am putting together the wiring and need to get a new firewall insulator as the old one was thrown out. I have the opportunity to buy an ACC one for almost half price, but it will still be around $130. Is it worth the extra money or can i just get a cheap $45 one. I have heard pretty bad things about almost all of them, not sure to the quality of the ACC one.

I did a cheap one but I also used Reflectix from Home depot right on the firewall first and dorn the trans tunnel before putting the cheap pad on. Helps reject a lot of the heat and this is a Florida car. Not original but I wasn't worried about that.

Even a so-so moulded pad would be superior to any flat pad. A compromise would be what I had to do on my "other" car. I dampened the die-cut cardboard, and when it softened, I gently moulded it to conform. Not as good as an OEM moulded pad, but far better than flat.

Would it work to do only the stick on insulation and not use a firewall pad?
Do you then mount the fuse box over the insulation?
Going to do this before long myself.

I just installed one in my 66 from NPD. I thought it fit very well and was impressed. It was $70. Has more of a rubbery type of face with insulation underneath. I had to modify it some for a few of my custom mod but it would have fit stock as-is

Good information, I think that for the extra $30 I'll get the good one. I had considered just using like a dynamat type of insulation but Id rather have it look and fit better for a few extra bucks. Im not going for a completely OEM but I would like it to look as good as I can.

I have the better one on my '65 and it looked and fit well. I now regret not adding an additional amount of heath shield or dynamat like product as well. Its surprising how much noise and heat are transmitted through the firewall.
